Principles of Producing Long Term Quality, Stable and Functional Fixed Partial Denture 1. Tooth morphology, form and function 2. Facial proportions, planes, lip lines and symmetry 3.

Implant restorations

Mucostatic are impressions that record the tissues with minimum displacement. Mucodisplacive are impressions that displace the tissues. The choice is made by the dentist on the basis of oral conditions, concept of the function of the tissues surrounding the denture and ability to handle the available impression materials.
