Comparison of the effects of cement removal from zirconia and titanium abutments: An in vitro study.

Statement Of Problem: Excess cement around dental implants is a significant cause of peri-implant inflammation. Research has focused on approaches to cement removal, the type of cement used, and the different instruments used for cement removal with titanium abutments. However, data comparing zirconia with titanium abutments are lacking.

Digital technology for performing a nasopalatine and greater palatine nerve block with a modified implant surgical guide: A technique article.

This article describes a computer-aided design and computer-aided manufacturing (CAD-CAM) technique to perform a precise nerve block of the nasopalatine and greater palatine nerves by using an implant surgical guide. The technique uses additional guide anchor pins planned and positioned for specific anatomic landmarks during guided implant surgical guide planning. A relief modification virtually designed on the intaglio surface of the surgical guide allows for palatal soft tissue distension following administration of local anesthetic.

Comparative Evaluation of the Effect of Laser Etching on the Shear Bond Strength of Crowns Cemented with Two Different Luting Agents: An In Vitro Study.

Purpose: The aim of this study was to compare the shear bond strength of crowns cemented on natural teeth after surface treatment of the enamel with an erbium-doped yttrium aluminum garnet (Er:YAG) laser.

Materials And Methods: Crown preparation was done for 40 full-metal crowns, and wax patterns with loops were cast in a cobalt-chromium alloy. The Er:YAG laser was used for surface treatment of some teeth, and teeth without surface treatment acted as the control.

Predictable prosthetic space maintenance during staged complete-mouth rehabilitation.

Staged complete-mouth rehabilitation to accommodate a patient's financial constraints during the course of treatment is presented. Clear acrylic resin added to the anterior cameo surface of the maxillary fixed complete denture (FCD) served as a space maintainer. The restoration of the maxillary FCD addressed the patient's chief complaint.

Comparison of maxillary anterior tooth width and facial dimensions of 3 ethnicities.

Statement Of Problem: As the cosmetic demands of patients increase, determining the appropriate dimensions of the maxillary anterior teeth has become increasingly relevant. The relationship between facial measurements and tooth size provide guidance for maxillary anterior tooth size selection. However, most publications on this topic have focused on the white population, and more data for tooth sizes and their proportions in other ethnicities are needed.
