ABSTRACT
This article reviews the rationale, techniques, and advantages of a guided full-arch immediatefunction implant treatment modality that includes placement of a prefabricated, bar-supported, monolithic polymethyl methacrylate acrylic (PMMA) prosthesis for edentulous and terminal dentition patients. A case presentation depicting the protocol shows it to be an effective and predictable approach to providing fullarch immediate fixed teeth, particularly when compared to conventional denture conversion techniques.

OBJECTIVE: To clinically evaluate the durability of an impressionless intraoral appliance (iNterra) system, fabricated using a direct/indirect technique. METHODS: Fifty-three (53) appliances were fabricated using the technique and followed for a median observation period of 301 days. Appliances were evaluated by calibrated operators for adaptation to teeth, retention, stability, and paresthesia, as reported by subjects, in addition to wear. RESULTS: All restorations (100%) were rated acceptable for adaptation to teeth, retention, and stability at placement. At the longest recalls, 96.2% of appliances survived without fracture. A similar percentage (96.0%) were rated acceptable for adaptation to teeth, retention, and stability. Paresthesia (reversible malodor) was reported in one (1.9%) case. In terms of wear, 98.1% of appliances delivered were rated as "no wear evident" or "evident but acceptable wear." CONCLUSION: Overall, the evaluators agreed that the impressionless system offered procedural efficiency advantages, was clinically viable, and should be a valuable option to practitioners considering appliance therapy to control parafunctional behavior.
