  MegaGen UkraineClinical Case : Missing on Mandibular Right Second Premolar (#4.5) and First Molar(#4.6), Pain on the Mandibular Right Second Molar(#4.7) p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; color: #c67838; -webkit-text-stroke: #c67838} span.s1 {font-kerning: none} A 35-year-old female patient in good general health, a non-smoker was referred for consultation and treatment of 4.7 tooth with pain (Fig.3,6) after hygiene visit. Also patient expressed the desire to restore a defect of missed right second premolar 4.5 and first molar 4.6 ( Fig.1,2).There were typical narrow ridge on the mandible in position of 4.5 and 4.6 (Fig.3,5). The strategy to overcome or avoid narrow ridge problem should be considered before surgery, the diameter and the design of an implant should be considered first, according to the alveolar bone shape. Patient was against any bone grafting and healing time before implants placement, so i prefer to use an implant with small core and platform size - AnyRidge.  p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; color: #c67838; -webkit-text-stroke: #c67838} span.s1 {font-kerning: none} Radiographic view of tooth 4.7 (Fig.4,6) showing a large periapical pathology and widened periodontal ligament space.

  Upper buccal cortical bone augmentation ..

  A 54 years old female patient was treated with a single implant in the position of #15. The natural second right premolar was previously endodontically treated and restored with a metal cast post and metal-ceramic crown 10 years ago (Fig.1). After the extraction of the fractured tooth (Fig.2) the region was cleaned from all inflammatory tissues and remaining cyst remnants and sterilized with ErYg laser (LiteTouch, Light Instruments, Israel). The procedure revealed excessive bone loss in the buccal area of the cortical bone of this region (Fig.3). A 4,5x10 AR implant was placed with a 70 level of stability (measurement with Mega ISQ). Autogenous bone and Bio-OSS graft (Geistlich Pharma AG, Switzerland) were placed and secured with an i-Gen B2-type membrane. Over all materials an Ossix-Plus (15x25) membrane was placed and stitches were applied (Fig.5,6). After 5 months the i-Gen membrane was removed and a healing abutment was placed. The final restoration was placed 3 months later for personal reasons of the patient. 12 months recall appointment revealed an over 3,5 mm bone regenerated area at #15, according to the dimensions of the i-Gen membrane originally used (Fig.7-12). Special thanks to Dr Antoniadou Maria for assisting the surgery and performing the prosthetic work.

  Immediately loaded implant utilizing ana..

  - Using an analog model for provisional restorations is usually done when using different softwares in the planning and restorative parts in the immediate loading protocol. - A fuse abutment has been used in this protocol for a safe immediate loading procedure.  - Attached are pictures with comments describing each step in this protocol using the 360DPS and 3shape Softwares. - One of the main challenges in this case has been using an engaging fuse abutment for the provisional restoration. since we were using a universal kit that no implant placement control (IPC) we have used the manual implant mount to place the Lab Analog into the analog model and marked the flat side on the surgical guide, then used the same implant mount with the the aid that marking on the surgical guide to mark where the flat side of the implant should be and also the correct vertical position marked by the (L) sign on the implant mount. - Provisional Prosthesis has been fabricated by Cairo dental designs Laboratory in Cairo Egypt. - I would like to dedicate a very special thank you to my dear friend and my Partner Dr. Mohamed Zaid from Cairo Dental Designs Laboratory. A great prosthodontist, he has been with me throughout the entire process from the lab work until the surgical procedure could not have done this without his help.

  Intedisciplinary management of a full mo..

  Intedisciplinary management of a full mouth rehabilitation: the smile design of the 50 plus generation using AnyRidge, MILA Kit and MegRhein Attachment systemA 67-year-old man presented for the prosthodontic rehabilitation of his partially edentulous jaws. His dental history included some extractions of  hopeless teeth and their replacement with fixed-teeth supported prosthesis. He expressed desire for the improvement of his chewing capacities and asked for changes in the appearance of his smile. Clinical and radiographic examination revealed a moderate to severe degree of alveolar ridge resorption, with major bone loss in the sites of tooth #33 and the right upper quadrant. Two implants were previously placed in position 43 and 33 to support a six units bridge, one of them failed.A treatment plan was prepared after a standard protocol that took into consideration the patient’s desires, treatment alternatives, and treatment costs. The plan included the surgical implant placement of 4 implants in each jaw and fabrication of a bimaxillary implant retained removable overdentures. We decided to maintain the implant #43 as an additional one to support the final mandibular overdenture, by the use of a Locator.Extraction of hopeless teeth and Socket PreservationThe first part of the treatment planning was the control of the chronic infections and extraction of all residual hopeless teeth with socket preservation technique to maintain the ridge volume. A temporary conventional complete denture was fabricated and used by the patient during a healing period of 4 months.Implant PlacementBecause of the adequate position of the temporary denture teeth, a decision was made to use a duplicate of the already fabricated dentures as a radiological and surgical template for the implant surgery planning and execution. The desired implant location was marked on the duplicate denture and stone cast. The duplicate denture was modified for the surgery by creating window-like openings in the areas of proposed implant sites. Vertical space analysis of the denture was performed for the selected attachment system (Locator Implants Attachment and MegRhein).Implant surgery included placement of the implants with the help of the surgical template. Implant surgery was carried out in a 1-stage surgical protocol. The implants were placed in the canine and first molar position for antero-posterior spread considerations. The implant site #16 presented a low height due to sinus pneumatization, a sinus lift was performed utilizing lateral window technique and MILA Kit (MegaGen, Kr). After completion, the complete dentures were relined with a soft-tissue conditioning material.  No complications were encountered during the surgical phase.  Five months later and after confirmation of the osseointegration, the patient presented for the definitive prostheses fabrication.Final Impression and Mounting to the ArticulatorThe maxillary and mandibular dentures were used as customized trays for final impressions. A closed tray impression technique was utilized. The Cuff height of the MegRhein abutments  were selected based on the existing soft tissue depth around the implants. One Locator Abutment was placed on implant #43. The final abutments were secured to the implants, and the impression copings were placed.The final impression was taken using a combination of high polyether  viscosity for borders registration and low viscosity polysulfide impression material placed inside the complete denture. Care was taken to center the denture during seating, and standard border molding procedures were used. After setting, the final impression was inspected and deemed acceptable. The duplicate denture was reinserted intraorally for the dentofacial evaluation, and the ideal location of the maxillary midline and incisal-occlusal plane was recorded. Standard photographs of the patients’ smile also were taken to be used in the laboratory for the denture tooth setup. The inter-maxillary bite registration was taken using a gothic arch tracer and the 3D position of the maxillary arch was registered using a facebow. The horizontal reference plane was the Camper Plane.The case was returned to the laboratory where standard protocols were used for the fabrication of the master cast. In the laboratory, implant analogs were attached to the impression copings, and a master cast was poured in type IV dental stone. The maxillary cast with the duplicate denture was positioned on the flat plane of the Kuwotech mounting plate. The occlusal registration tray was seated on the upper master cast, this one was secured to the index tray and mounted to the upper member of a semi-adjustable articulator (Op Finder, Kuwotech, Kr). The mandibular and maxillary master casts were articulated to each other with a centric relation record using the Gothic Arch Tracer, and the mandibular cast was mounted to the lower member of the articulator. Artificial denture teeth were selected based on the references provided by the existing dentures and the patient’s preference for a specific shade. The maxillary denture tooth setup was completed using the references provided by the Digital Smile Design Concept.The maxillary wax-trial denture was placed intraorally, and tooth position was evaluated using standard prosthodontic protocols. Proposed changes to the tooth position were recorded.Metal Framework FabricationThe selected attachments (Processing Capa) were placed on the top of the abutments. Undercut areas of the attachments were blocked out with wax. One layer of the baseplate wax was placed in the edentulous areas on the master cast. The refractory cast was fabricated by duplicating the master casts. The metal-reinforcing framework was waxed in a mesh-like form on the refractory cast, with leaving an adequate space for the resin material over the metallic caps. Several vertical retentive elements were waxed around the attachments on the framework. The framework was fabricated in the chrome-cobalt alloy using standard “lost wax” production techniques. The fit of the framework was verified, and its surface was finished and polished. The framework was positioned on the master cast.Prostheses Fabrication and DeliveryThe maxillary denture tooth setup was completed using the mounting plate, the the mandibular teeth mounted against the maxillary denture tooth setup. The wax-trial dentures were returned to the clinic for the try-in. The fit, occlusion, and esthetics of the prostheses were verified intraorally and approved by the patient.The prostheses were processed with a heat-polymeized acrylic resin using a standard compression molding protocol. The surfaces of the dentures were finished and polished. Processing clips were replaced with the light retention clips (Yellow for MegRhein and Blue for the Locator Attachment) respectively in the  the mandibular and maxillary overdenture.In the clinic, abutments were attached to the implants and torqued to the manufacturer’s recommended value. The metallic female housing are picked-up to the framework with an autopolymerized acrylic resin, directly in the patient’s mouth, this will allow to take into consideration the soft tissue depression during function and better force management of the occlusal forces around the implants. The prostheses were seated, and excessive pressure areas were adjusted with the help of pressure-indicatingpaste.The desired occlusal scheme was verified and adjusted intraorally. The patient received maintenance instructions, and the recall appointments schedule was established. At the subsequent recall appointment, the patient expressed satisfaction with the treatment.Conclusion Among different treatment options, an implant-retained overdenture is a simple, cost-effective solution in the rehabilitation of the edentulous jaws. The overdenture design includes a metal-reinforcing framework and uses prefabricated stock abutments and hinge-type resilient attachments for its retention. The advantage of such type of prosthesis is unequivocal on the advantages of the implant-anchored prosthesis (eg, improved quality of life for the patient and long-term preservation of the remaining alveolar and basal bone). This prosthetic option reestablish the principle functions of the masticatory system: swallowing, incision and phonation, in additionto the esthetic and smile rehabilitation.

  Placement of Dental Implants in the Comp..

  Patient K., 42 y.o., admitted to the dental clinic of the “Reaviz” Medical University with complaints about difficulties in chewing the food due to the missing 2.6 tooth. Following the examination it was identified that a capsule-shaped septum 7 mm in height exists in the maxillary sinus positioned in the medio-distal direction throughout the total length of the sinus bottom. The thickness of the alveolar crest in the projection of the 2.6 tooth is 5 mm. The obtained data made it obvious that the standard sinus lift procedure would yield no positive results. Therefore a decision was made to perform the operation using the Samuel Lee’s patented  procedure and the crestal sinus lift MICA Kit by MegaGen.

  Expanding the Indications for the Immed..

  Case StatementA female patient B. admitted to the dental clinic of the “Reaviz” Medical University with complaints of difficulties of chewing the food due to lack of fixation of the bridge-type structure of the right maxillary. Examination DataFollowing removal of the orthopedic construction it was identified that  tooth 1.7 has indications for extraction (root caries, fracture in the mesio-distal plane), tooth 1.6 is missing. The abutment tooth 1.5 is in good condition.X-Ray Examination DataFollowing the study of the CT data in the position of the 1.7 tooth counter-indications were identified for the placement of the implant immediately after the extraction of the tooth. Primary stability of the implant seemed impossible due to the following reasons:1.The bottom of the peridental socket is directly adjacent to the maxillary sinus; implant stability is impossible in the periapical tissue;2.Placement of the implant in the interradical septum is impossible (septum height: 6 mm, thickness: 2.5 mm max);3.Stabilization of the implant in the peridental socket walls with conventional implanting systems is not possible; max diameter of the socket is 6 mm.   Therefore, the use of the conventional implant systems would require delayed implantation which would increase the treatment term (3 months) and the number of invasions.Treatment Plan1.Place the AnyRidge Ø 5,5x10 implant in the anodentia zone;2.In the position of the tooth 1.7 perform immediate implantation using the AnyRidge Ø7x10 dental implant. Sufficient primary stabilization of the implant is planned to be achieved from the aproximal walls;3.In order to mitigate the soft tissue defects following the extraction of the tooth and to increase the gum volume (form the tissue barrier) it was planned to use the epitelial autotransplant from the palate area on the pedicle.4.Following the osteointergation process, place the healing abutments. 5.Orthopedic rehabilitation using customized titanium abutments.

  Complex implant case by a patient with ..

  A patient which has a specialised produced protheses on korber konus construction because of cheilo-palatal-schisis had a problem because the supporting teeth were failing. This patients protheses was in us efor over 45 years. So it was important to save as much of there original protheses as possible. In this case we restore the retention of this protheses with kerators on anyridge implants in de the upper jaw. We chose the anyrdige implants because we where expecting type 3 bone quality and love to have some retention in the sponges bone. We had to change the biotype of the gum after fase one surgery and did this in de second stage. There is a picture from the transferring her old prothese in a new prothese and healing after onder year of function.
