CLINICAL An Interocclusal Recording Method for the Fabrication of Full-Arch Implant-Retained Restorations Gregory-George Zafiropoulos, DDS, Dr.Dent, Dr.habil1* Aiman Abdel Galil, Dipl.Dent.Techn2 Giorgio Deli, DDS, MD3 The prosthetic rehabilitation of full arches with implants requires exact impression and bite registration. In this report, we describe the application of a simple method that uses a duplicate of the full denture as a mounting guide, which allows the accurate recording of the maxillomandibular relationship and bite registration while expediting this process for the treating dentist. Case reports of 2 patient are used to illustrate this method, which is independent of the implant system used, can be applied for both fixed and removable restorations, and reduces chair time. Key Words: implant denture, interocclusal distance, maxillomandibular relationship, implant prosthodontics, implant prosthetic INTRODUCTION A full denture is usually delivered after tooth extraction or implant insertion in a fully edentulous arch and is used until the final restoration is performed. A well-designed full denture should fulfill the following criteria: (1) correct vertical height and maxillomandibular relationship; (2) accurate occlusion; (3) appropriate choice of teeth with regard to shape, length, width, and position; (4) adequate lip support; and (5) proper function and esthetics that meet the patient's expectations. The final restoration should fulfill or surpass these requirements. Obtaining a correct impression and accurately evaluating the interocclusal relationship (eg, interocclusal distance, occlusal recording, and determination of the exact position of the placed implants) are often challenging and time-consuming tasks.1,2 In this case report, we describe the use of an easy and reproducible technique that allows the 1 Dental Center Blaues Haus, Dusseldorf, Germany, and Division of Periodontology, Catholic University, Rome, Italy. 2 Dental Center Blaues Haus, Dusseldorf, Germany. 3 Division of Periodontology, Catholic University, Rome, Italy. * Corresponding author, email: zafiropoulos@prof-zafiropoulos.de DOI: 10.1563/AAID-JOI-D-11-00232 interocclusal relationship, occlusal recording, and esthetic factors used initially to produce the full denture to be transferred as a template for the fabrication of the final full-arch implant retained fixed or removable restoration. CASE REPORTS Case 1 An 80-year-old male nonsmoker in good general health, who was not regularly taking any medication or drug, was referred for implant placement and mandibular prosthetic restoration in February 2010. After extraction of multiple mandibular teeth that had been rendered unsalvageable by advanced periodontal disease, a denture was fabricated (Figures 1a through b and 2a). Tooth 18 was temporarily retained until the fabrication of the final restoration to stabilize the denture through an Akers clasp (Figure 1c). For additional stabilization of the denture, 2 provisional implants with ball attachments were placed in areas 22 and 24 (Table 1; Figure 2b), and the appropriate retention element was embedded into the denture's base. Four months after the extraction sites had healed and denture sores were eliminated, the function and esthetics of the denture were optiJournal of Oral Implantology 357
