PURPOSE: The introduction of the four-splint technique in our hospital in 1997 made possible the reproducible centric condyle positioning in bimaxillary osteotomies, while taking the auto rotation of the mandible into consideration and avoiding steps in the mandibular osteotomy line. PATIENTS AND METHODS: From 1981 to 2002 a total of 622 patients underwent bimaxillary osteotomy surgery. During 1981-1997 a total of 395 patients (63.5%) underwent surgery without or only with centric condyle positioning in sagittal ramus osteotomy of the mandible. During 1997-2002 a total of 227 patients (36.5%) underwent surgery with continuous centric condyle positioning with the four-splint technique. RESULTS: In patients with preoperative functional disorders, surgery with continuous centric condyle positioning resulted in statistically significant (p<0.05) improvement compared to those who underwent surgery without continuous centric condyle positioning. CONCLUSION: The results confirm the indication for continuous centric condyle positioning in bimaxillary osteotomies.
During the past 30 years, there has been a growth of implant courses in dental schools at the predoctoral level to meet a burgeoning demand. At the same time, there has been a concomitant reduction in curriculum time devoted to clinical and technical aspects of complete denture construction. There will be a sizable cohort of patients with limited natural dental landmarks seeking implant reconstructions that may be difficult for the general practitioner to restore. This article reviews basic prosthodontic principles and procedures that are important to understand when designing an implant prosthesis.
