  • Transferring condylar and anterior guidance on an articulator is essential to the diagnosis of a patient for full mouth reconstruction. In this clinical report, ARCUS digma I system was used to measure inherent condylar guidance of a patient requiring full mouth reconstruction in preoperate treatment, and the patients was given provisional restoration based on a functional anterior guidance. Then, ARCUS digma II system was used to mount the final casting model on an articulator, and the definitive prosthesis was placed in the patient. An esthetic and functionally proper clinical result regarding inherent condylar path of the patient was observed, and results from comparison of the two systems are given in this case.

  • One of the important things in the full mouth reconstruction is the determination of therapeutic position. Centric jaw relation is used as a therapeutic position for the full mouth reconstruction. There are several techniques associated with recording this position. Five clinically acceptable techniques are as follows: 1) Swallowing or free closure, 2) Chin point guidance, 3) Bimanual method 4) Myo-monitor technique, 5) Anterior deprogrammer. Centric relation obtained utilizing the anterior acrylic resin platform in this case. Another important thing in full mouth reconstruction is provisional restoration. Provisional restorations are an excellent diagnostic instrument, especially in full remain esthetics, phonetics, function, parafunction, and dysfunction after evaluation and acceptance through clinical trial with the provisional restorations should be accurately transferred to the final restorations to ensure the same clinical success. Especially, anterior guidance should be accurately transferred to the final restorations. An accurate anterior guidance is critical for optimal esthetics, phonetics, comfort, function, stress minimization, and longevity of teeth and restorations. To record optimum anterior guidance, customized anterior guide table is used in this case. Considering previously mentioned points, we did successive treatment. And it resulted in a better situation esthetically and functionally. Followings are what we cared in treating a patient in this case. 1) Accurate centric relation recording 2) Accurate transference of anterior guidance to the final restorations.

  • Lower lip reconstruction in cases with a full-thickness defect over one-third of the vermilion is challenging. Numerous conventional techniques have been applied with unsatisfactory surgical outcomes because of microstomia and oral commissure blunting due to shortened horizontal lip length. Herein, we present a case in which a full-thickness lower lip defect of more than one-third of the horizontal lip length was covered with a novel mucosal roofing flap reconstruction to minimize the loss of horizontal lip length and to preserve mouth opening. No recurrences or metastases were observed during 3 years and 6 months of follow-up, with horizontal lower lip length maintained and mouth opening of 2.5 finger breadths.

  • This case study is aimed at introducing a full-mouth rehabilitation of a patient with severe tooth wear using fixed prosthesis. This is a case report of a patient with severe wear dentition with changing vertical dimension. In line with using prosthetic treatment, patient adaptation was verified with provisional restorations followed by diagnostic wax-up. Function, esthetics, and occlusal stability were verified during a 4-week follow up period. Prosthodontic reconstruction based on systemic analysis, diagnosis, and treatment plan led to satisfactory results after delivery of definitive prosthesis. Prosthetic treatment of severe wear dentition was functionally and esthetically successful. Dentists and dental technicians would be able to develop better treatment approaches using fixed dental prosthesis.

  • Reconstruction of the lower lip requires consideration of several factors. There should be retained sensation, maintenance of oral sphincter function, and a large enough opening for the mouth. In addition, it is important to achieve an aesthetically acceptable appearance. Webster's modification of Bernard operation is one of good methods which satisfy above mentioned goals. The purpose of this article is to present the results and review the perioperative problems after reconstruction of the lower lip by this operation. We reviewed seven patients after surgical reconstruction by the same method between January of 1996 and December of 2003. Five patients were male and two were female. The mean follow-up period was 15 months. We obtained functionally and cosmetically acceptable appearance after reconstruction. Most of the reconstructed lower lips were large enough for full mouth opening, but one patient required additional commissuroplasty, and one other patient was treated with wound revision for dehiscence resulting from protrusion of mandibular lateral incisor tooth. All other patients accepted their facial appearance. In conclusion, careful planning and consideration for dental problems and proper closure tension may ensure satisfactory outcome & lower lip competence, when using this modified operative method for lower lip reconstruction.

  • Purpose: Mobius syndrome is a rare congenital disorder characterized by facial diplegia and bilateral abducens palsy, which occasionally combines with other cranial nerve dysfunction. The inability to show happiness, sadness or anger by facial expression frequently results in social dysfunction. The classic concept of cross facial nerve grafting and free muscle transplantation, which is standard in unilateral developmental facial palsy, cannot be used in these patients without special consideration. Our experience in the treatment of three patients with this syndrome using transfer of muscles innervated by trigeminal nerve showed rewarding results. Methods: We used bilateral temporalis muscle elevated from the bony temporal fossa. Muscles and their attached fascia were folded down over the anterior surface of the zygomatic arch. The divided strips from the attached fascia were passed subcutaneously and anchored to the medial canthus and the nasolabial crease for smiling and competence of mouth and eyelids. For the recent 13 years the authors applied this method in 3 Mobius syndrome cases- 45 year-old man and 13 year-old boy, 8 year-old girl. Results: One month after the surgery the patients had good support and already showed voluntary movement at the corner of their mouth. They showed full closure of both eyelids. There was no scleral showing during eyelid closure. Also full closure of the mouth was achieved. After six months, the reconstructed movements of face were maintained. Conclusion: Temporalis muscle transfer for Mobius syndrome is an excellent method for bilateral reconstruction at one stage, is easy to perform, and has a wide range of reconstruction and reproducibility.

  • Congenital hypoplasia of the depressor anguli oris muscle is a rare cause of asymmetrical crying facies in newborns. The clinical manifestations range from mild to severe asymmetry and may persist up to adulthood. In the current case, the patient did not exhibit other congenital anomalies or paralysis of other branches of the facial nerve. This adult patient presented with severe asymmetrical lower lip deformity during full mouth opening since birth. A chromosomal study for the detection of 22q gene deletion yielded negative results. The electromyography findings of the lower lip were insignificant. Depressor labii inferioris muscle resection was not effective, but bidirectional (horizontal and vertical) fascia lata grafting improved the aesthetic appearance of the asymmetrical lower lip. The patient showed improved lower lip symmetry during full mouth opening at 1 year after the surgery. Therefore, the details of this rare case are reported herein.

  • This is a case report about patient who had suffered from degenerative joint disease and treated by TMJ reconstruction with condylar prosthesis. The patient visited Korea University An-am hospital on 2007 complaining symptom about both TMJ pain, mouth opening limitation and open bite. From CT view there was severe resorption of both condylar head, therefore condylar prosthesis reconstruction was planned. After 3D RP model analysis for preparation, the patient was operated under general anesthesia for condylar prosthesis reconstruction and the symptom was alleviated. (increased mouth opening, reduced anterior open bite, full mouth occlusal contact achieved) Follow up was carried out monthly, but after this, patient refused follow up. After 26 months from the operation, the patient revisited for anterior open bite. In clinical evaluation, occlusal contact was remained, but anterior open bite was relapsed. From cephalometry analysis, severe resorption of glenoid fossa was found. Therefore, Autogenous disc reconstruction with alloplastic material was planned on August 2009. After another surgery, condylar prosthesis was regained its normal position in glenoid fossa, and occlusion was recovered properly.

  • Recently, digital technology has become increasingly prevalent in the dental clinic. Using a milling machine for clinic, it is possible to produce provisional restoration inside the clinic. This can promote large clinical cases such as full mouth rehabilitation with the help of a tabletop scanner, which is capable of semi-adjustable articulator equipment, and a powerful dental CAD software with excellent user convenience. In this case report, a full-mouth rehabilitation was done with digital technology to a 55 year-old female patient, who has lost vertical dimension through the attrition, and has got inclined occlusal plane with unplanned and repeated dental reconstruction. Through the design and milling of the provisional restoration in the clinic and the duplication of these provisionals by double scanning technique, a good functional and esthetic result could be achieved.

  • Peri-implantitis appears in almost 20% of patients who received implant treatment, and increase in its number is inevitable as time goes by. Although it can be treated by both non-surgical and surgical procedures, in cases which include severe bone loss, explantation and rehabilitation may be necessary. Careful treatment planning and considerations to prevent recurrent peri-implantitis should be taken into account. In the following case presented, a patient with chronic periodontitis and peri-implantitis was successfully rehabilitated after removal of several implants. Extraction and explantation of multiple teeth and implants were followed by full mouth reconstruction with fixed implant prostheses on the mandible and implant retained overdenture on the maxilla. Surgical and prosthetic measures to prevent recurrent peri-implantitis were taken into consideration.
