Generic terminology for endosseous implant prosthodontics.

Implant dentistry has become an integral treatment modality in the restoration of the complete and partially edentulous patient. Most practitioners have been educated by manufacturer-sponsored courses oriented to the use of a specific implant system. The ever-increasing number of implant systems has made the names of many implant components product-unique and confusing. Fortunately, a prosthetic continuity exists between most implant systems. A generic terminology for endosseous root-form prosthodontics is presented that allows effective communication between members of the profession.

Issues in bone mechanics related to oral implants.

The development and maintenance of the dental implant-to-tissue interface is clearly of paramount importance in the determination of clinical success. Yet, the precise mechanism with which bone responds to mechanical load remains unknown. A review of current thought on the performance of cortical and cancellous bone as structural foundations for dental implants is provided, with particular emphasis on the influence of its three-dimensional architecture at the macroscopic level. The mechanical response of bone is reported to depend upon the direction, magnitude, rate, and duration of loading. Quantitative relationships have been established to correlate cancellous bone strength and stiffness to its apparent density. Such data provide useful insights into the modeling/remodeling response of bone tissue, which is arguably the ultimate predictor of implant longevity.

Reconstruction of maxillary alveolar defects with mandibular symphysis grafts for dental implants: a preliminary procedural report.

Partially edentulous patients with alveolar defects contraindicating implant placement were treated with bone grafts obtained from the mandibular symphysis. Complications encountered were minor and uneventful. Evaluation 4 months after surgery revealed minimal graft resorption, thus implant placement was possible in all potential sites. Advantages of the symphysis graft include easy access, availability of greater quantities of bone over other intraoral donor sites, low morbidity, no hospitalization, minimal discomfort, no alteration in ambulation, and no cutaneous scar. Compared with other bone regenerative methods for implant placement, a superior quality of bone was found and a shorter healing period is required. Results of this preliminary clinical investigation demonstrate that chin grafts offer a viable alternative for reconstruction of alveolar defects prior to dental implant placement.

Force transfer in implant dentistry: basic concepts and principles.

The mechanism and efficiency of force transfer by dental implants to contiguous biological tissues are clearly important determinants in the development of the implant-to-tissue interface and, indeed, implant longevity. Whether a clinician seeks to gain a better understanding of implant design rationale and/or to implement biomechanics concepts in patient care, a fundamental, yet clinically relevant, understanding of biomechanics is required. A primer in force transfer is thus presented, with particular attention focused on implications for the long-term success of dental implants and restorative procedures. Forces and their components, moments, force transfer mechanisms, impact, and stress-strain relationships all influence clinical decisions and treatment plans.

Autogenous bone grafts for endosteal implants--indications and failures.

The use of autogenous bone grafts (ABG) combined with endosteal implants permits to restore patients with conditions of extreme bone atrophy or with very demanding final results. The improvement of the biomechanics conditions, moment forces, C/I ratio, ridge relationship, length, diameter, number and location of the implants and esthetics improve the prognosis of the restoration. Large segments of autogenous bone is harvested from the iliac crest or cranium. Excellent autogenous membranous bone can be obtained intra-orally from the mandibular symphysis when smaller dimensions are needed. Indications for treatment with autogenous bone grafts are presented following the Misch/Judy available bone classification. In division C-w ridges, ABG improve the width of the ridge to permit the placement of root form implants. In Division C-h ridges, ABG improve the height available for implant placement, and permits to obtain a FP-1 or FP-2 result. In Division D ridges, ABG represent the treatment of choice. RP-4 restorations are encouraged. High success rates obtained by the author depend upon strict patient evaluation, treatment planning, careful placement of the minimum number of implants with the bone grafting procedure only to immobilize the grafted segment, progressive bone loading during the prosthetic phase, proper soft tissue management and sufficient number of implants for the planned prosthesis.

Post-operative maxillary cyst associated with a maxillary sinus elevation procedure: a case report.

Proper diagnosis, treatment planning, and surgical manipulation of the posterior maxilla require a thorough knowledge of the anatomy, physiology, and pathology associated with the maxillary sinus. This case report of a post-operative maxillary cyst diagnosed following routine post-operative examination of a sinus elevation procedure illustrates the need for a meticulous surgical technique, proper management of complications, and routine, long-term follow-up. With the increased utilization of sinus elevation techniques, reports of this destructive lesion may become more common.

Dental education--meeting the demands of implant dentistry.

Implant education is undergoing a transition from short, often superficial, continuing education to extended, hands-on experiences, based on clinical case studies. Dental schools previously ignored the need for in-depth implant education. Policy decisions related to future education are being considered in most dental undergraduate and postgraduate curricula. A broad-based implant education concept is proposed to meet the demands of a rapidly developing discipline.
