Complete artificial dentition supported by endosseous implants: a case report of total in-office treatment.

This case report demonstrates the construction of a complete restoration of the dentition by the surgical placement of endosseous titanium implants that support a fixed prosthesis in each jaw. The positioning of the implants and teeth in the prostheses are important factors for a successful long-term result. Distribution of the occlusal biting forces over as many implants as possible is important. Off-axial occlusal biting forces should be diverted to the anterior prostheses, where the forces are not as great and the posterior teeth are designed with flat occlusal surfaces that separate during excursionary chewing movements. Medial mandibular flexure caused by the contraction of the medial pterygoid muscle can be addressed by constructing the prosthesis in segments. This is so as not to have a rigid entity encased in flexing bone that may induce stress to the bone, leading to loss of implant integration and failure. Segmenting also insures an appropriate fit of the prosthesis with respect to casting and porcelain firing distortion. Lip support by means of a flange in the prosthesis may be necessary when there has been a large amount of bone loss from edentulous resorption. Cleaning and maintenance of the prostheses every 3 to 6 months is essential.

[Exchangeable system synthetics-rider at the bridge-joint prosthetics].

In order to improve the prosthetic supply, a clam-on system for bar-joint-mandibular dentures has been developed. When replacing clamp No. 1 by clamp No. 2 both the vertical translation and the frontal rotation of the prosthesis are ensured over a longer time of function. Placing at disposal ready-made plastic bar-joint elements facilitates the clinic and the laboratory technology for making the bar-joint-mandibular denture.

[Implantology in oromaxillofacial surgery].

Since the last 30 years endosseous implants are a well established treatment technique in maxillofacial surgery. Implants are used in the rehabilitation of patients having lost parts of maxilla or mandible due to tumor surgery, or which due to radiotherapy have problems tolerating mucosa-borne dentures. The implant borne prosthesis will aid to regain live quality to those patients. Improvement of live quality is also the result when epithetic reconstructions of soft tissue defects in the face are stabilized by extraoral implants. Aim of the paper is to give an overview on important implant related pathophysiological osseous healing patterns, discuss methods to influence these processes, to show correction possibilities for the bony bed and highlight their indications as well as to inform about clinical experiences with endosseous implants.

Implant site development and alveolar bone resorption patterns.

Resorption of the alveolar ridges after tooth extraction can mandate site development (preparation) by augmentation, grafting, or both before implants can be placed. The fabrication of successful implant prostheses generally can be accomplished only if the artificial teeth are placed in the same position as was occupied by the natural teeth they are replacing. A knowledge of resorption patterns is necessary for satisfactory implant placement.

The successful use of osseointegrated implants for the treatment of the recalcitrant periodontal patient.

This study reports the successful use of osseointegrated implants to replace teeth in patients whose periodontal disease has been categorized as recalcitrant. It includes partially and totally endentulous jaws. A total of 309 implants placed by two periodontists practicing in traditional office settings were included in the survey. Of the 132 mandibular implants, 4 failed, for a success rate of 97%; and 3 of the 177 maxillary implants failed, for a success rate of 98%. There were 21 implants placed in 1985; 38 in 1986 and 1987; 185 from 1988 to 1990; 42 in 1991; and 23 in 1992. The report includes 42 mandibular and 50 maxillary prostheses, none of which has failed. One female mandibular case was converted from 2 posterior free-standing to a full arch prosthesis when the anterior teeth failed periodontally. These results demonstrate that individuals with a strong susceptibility to periodontal disease can be treated successfully with osseointegrated implants.

[Orthognathic surgery of the edentulous: a particular form of preprosthetic surgery].

It is not unusual to find patients who have lost posterior teeth or who are totally toothless, approaching our dental surgeon colleagues in cases of difficulties, and even prosthetic impossibility, nearly always associated or in relation with skeletic maxilo-mandibular imbalance. Orthognatic surgery of the toothless should thus satisfy the essential need for prosthesis but should also re-establish the unbalanced facial architecture which can be the only guarantee of a stable result. This therefore requires true pre-prosthetic surgery in which clinical analysis, cranial-facial architectural analysis and great care in making the provisional and final prosthesis, constitute the essential stages of diagnosis and therapy.

New surgical procedures of the osseointegration technique A.M. Brånemark.

This paper aims to give a few personal comments on some new surgical procedures, which have during later years been introduced for use in severely resorbed jaws, treated with the osseointegration technique a.m. Brånemark. The methods presented are: (a) the use of 5 mm diameter implants, (b) the bone tissue regeneration technique, (c) the local onlay grafting procedure, (d) the sinus lift procedure, (e) the pterygoid implant technique, and (f) the nerve transposition procedure. The paper was originally presented at the Nobelpharma Team Day Conference in Sydney, November 1992.

Ann Otol Rhinol Laryngol [Suppl].

Mandibular replacement subsequent to major extirpative head and neck surgery is predisposed to complications in the best of hands. The most suitable prosthesis appears to be the previously resected mandible, both from the standpoint of antigenicity and configuration. This study establishes that in the canine mandible a healthy, revitalized osseous network is reestablished subsequent to resection, freezing and replacement of the mandibular body when the graft is immobilized. The neoosteogenesis is borne out by in vivo (technetium 99, methylene diphosphonate scanning) and histopathological (tetracycline fluorescence and polarizing microscopy) studies. This early work in the canine suggests the potential for application in the human when the procedure is further refined and perfected.

Vertical distraction osteogenesis of fibula transplant for mandibular reconstruction: a case report.

Bone continuity defects in the mandible are caused by tumor surgery, trauma, infection, or osteoradionecrosis. Today, reconstruction of long-span mandibular defects with a free fibular flap is a routine procedure. However the bone height of the mandible after reconstruction is about half that of the dentulous mandible. Therefore, the deficiency in bone height makes implant placement impractical. In our case, because it was necessary to restore the mandibular height, a vertical distraction osteogenesis was performed on the grafted mandible of the patient who was referred to our clinic with a reconstructed mandible owing to a gunshot injury. As a result, the vertical discrepancy between the fibula and the native hemimandible of the patient was corrected. And the placement of dental implants was performed without any complications. In conclusion, we believe that the vertical distraction osteogenesis of free vascularized fibula flaps is a reliable technique that optimizes implant positioning for ideal prosthetic rehabilitation.
