Metal-ceramic screw-retained implant fixed partial denture with intraoral luted framework to improve passive fit.

Passive fit of a long-span screw-retained implant prosthesis is an important criteria for the success of the restoration. This article describes a technique for fabricating a ceramometal implant fixed dental prosthesis (FDP) for a long-span partially edentulous situation by altering the conventional screw-retained design. The possibility of a passive fit is maximized by intraoral luting of the cast frame to milled abutments, and the potential framework distortion during fabrication is compensated to a major extent. Retrievability is ensured by screw retention of the prosthesis to the implants. Compared with conventional porcelain fused to metal screw-retained FDP, this prosthesis is relatively inexpensive to fabricate.

Restoration of failing maxillary implant-supported fixed prosthesis with cross arch splinted unilateral zygomatic implant: a clinical report.

Management of one or more failing distal implants in an implant supported fixed prosthesis in a completely edentulous maxilla creates a challenging situation. Restoring immediate function with additional implants in such a situation can be a challenge considering the loss of supporting bone, need for grafting, age, and the patient's desire for immediate fixed dental prosthesis. This clinical report describes a situation where a zygomatic implant has been placed unilaterally and splinted with osseointegrated conventional implants by an immediate fixed provisional restoration.

Intraoperative and perioperative complications in anterior maxillary osteotomy: a retrospective evaluation of 103 patients.

PURPOSE: To study the intraoperative and perioperative complications associated with anterior maxillary osteotomy (AMO), and assess its safety and predictability in orthognathic surgery. PATIENTS AND METHODS: We performed a retrospective evaluation of 103 patients undergoing AMO as a single procedure, or in combination with other osteotomies over a period of 5 years, with a mean follow-up of 3 years. RESULTS: Twenty-seven (26.2%) patients in our series of 103 had complications of varying severity: 43.3% of these were soft tissue-related, and 36.6% were attributable to dental causes. All other complications accounted for the remaining 20%. CONCLUSION: Although its indications are limited, AMO is a safe and reliable procedure in routine orthognathic surgery.

Cone-beam computed tomography in the management of dentigerous cyst of the jaws: A report of two cases.

Cone-beam computed tomography (CBCT) is an emerging technology finding application in all branches of dentistry. The current series highlights the application of CBCT in the preoperative assessment of dentigerous cyst of the jaws.

Intraoral framework pick-up technique to improve fit of a metal-resin implant prosthesis.

The achievement of passive fit is an important prerequisite for the prevention of complications in full-arch screw-retained implant prosthesis. With cemented prosthesis, the cementation compensates for the discrepancies in the cast framework, but the lack of retrievability seems undesirable. The aim of this paper is to propose a modified screw-retained prosthesis design for complete arch implant fixed rehabilitation. A technique for the fabrication of a full-arch metal-resin implant-supported screw-retained prosthesis is described. Cementation of the framework to the abutments intraorally improves the passivity of fit of the prosthesis on the implants. Maintenance of screw-access channels in the final prosthesis ensures retrievability. The metal-resin design allows for easy repair and maintenance. The prosthesis is cost-effective compared to conventional options and can be employed as a viable treatment alternative when considering metal-acrylic resin complete arch fixed prosthesis.
