Using an existing denture to design a radiographic template for a two-implant mandibular overdenture

Abstract

This article introduces a technique for modifying an existing mandibular complete denture for use as a radiographic template with a radiopaque light-activated calcium hydroxide (Ca(OH)2) preparation. This allows prosthetically-driven treatment planning and surgical placement of 2 implants to support the existing mandibular denture.

Implant Stability and Marginal Bone Loss in Mandibular Implant Retained Overdenture Cases: A Comparative Study Using Two Stud Attachment Systems

“…16 CBCT was selected for preoperative assessment of the implant sites in this study as the traditional radiographs, such as panoramic and periapical films have been found to be of limited diagnostic value owing to their 2-dimensional nature, While CBCT allows the capture of cross-sectional images at lower radiation doses with superior quality of the images and less expenses when compared to the conventional computed tomography (CT). 17 During the construction of the radiographic template, the amalgam acrylic resin powder mix of 1:3 by weight was used as a radio-opaque marker as it have high visibility properties at all areas of scans because it provides distortion free medium with very low costs and simplicity compared with other radio-opaque indictors. 13 A standardized implant size was used for all patients to eliminate the effect of implant surface area on the integration process as the difference in implant length and or diameter may influence the pressure per unit area in the supporting bone.…”

Basics of navigation implant prosthetics planning

“…It is advised that adhesives should be applied on the mucosal side of the prosthesis before radiography as well. Perforations, in which the radiopaque materials are placed, are formed within acrylic teeth [19,20]. The other option is fabricating the master cast based on complete denture.…”

Evidence‐Based Criteria for Differential Treatment Planning of Implant Restorations for the Maxillary Edentulous Patient

“…64 If the existing maxillary denture has been constructed at the appropriate OVD, and the anterior and posterior planes of occlusion are suitable, based on esthetic, 65 phonetic, 66 and biometric references, 67 a duplicate denture/radiographic and surgical template can be fabricated. 68 If the existing denture is not acceptable, an idealized wax-up is required before duplication. AbuJamra et al 69 described a laboratory technique to visualize the interarch space available for implant prosthetic restoration of an edentulous patient.…”
