Quality assurance of ceramic dental restorations by photographic transillumination
Quality assurance of indirect restorations should be performed by the dental laboratory before delivering the prosthetic parts to the clinician. Ultimately, it is the clinician’s responsibility to inspect and ensure, within the limits of clinically available technical and technological means, the quality of the prosthesis prior to insertion. Transillumination techniques in dentistry have been described as an aid in diagnosis as well as during the execution of various clinical procedures, including those for interproximal caries detection,1 endodontic visualization of dentinal defects,2 surgical localization of retained roots,3 location of the maxillary sinus floor and septa during sinus augmentation procedures,4 diagnosis of occult submucous cleft palate,5 and as a facilitator during arthroscopic puncture.Adaptation of an interim partial removable dental prosthesis as a radiographic template for implant placement
Historically, dental implant placement was driven by the amount of existing bony support and the implant fixture was positioned where bone was abundant. Compromised biomechanics, esthetics, cleansability, unusable implants, and biological failure have resulted from not envisioning the definitive restorative and functional outcome.1
