Fabrication of a surgical guide with help of a milling machine by ridge mapping method.

Optimizing the prosthetic result by customization of a surgical guide should be a major consideration in the implant placement. The design of the surgical guide must account for several factors, including position of the implant, the tissue present, and the anticipated prosthesis. The objective of this article is to present a technique for fabrication and customization of surgical guide with the help of ridge mapping procedure and a milling machine.

An evaluation of retention and marginal seating of Ni-Cr alloy cast restorations using three different luting cements: an in vitro study.

Context: Clinical and laboratory studies regarding performance of recently introduced luting cements: Adhesive resin cement and resin-modified glass ionomer cement (GIC), are limited.

Aims: To compare the retention and marginal seating of Ni-Cr alloy restorations using newer luting cements: Resin-modified GIC and adhesive resin cement with those of the oldest cement, zinc phosphate.

Materials And Methods: Thirty maxillary premolars of similar sizes were prepared to receive cast metal copings.
