Masticatory function is more important than esthetics in posterior fixed restoration. The usual technique-mounting the casts on a semi-adjustable articulator, etc. -cannot make all patients satisfied with their restorations. For example, functionally generated path technique can be an easier and more satisfactory method in the restoration of group function. These clinical reports describe various approaches for occlusal restoration of relatively simple posterior fixed protheses according to patients occlusal patterns. The 3-unit bridge restoration is one of the most popular treatment options in prosthodontics. Because dentists have much experiences of it, they restore a missing span of one tooth mechanically, that is, without special consideration. While esthetics is important in making an anterior 3-unit fixed prostheses, mastication is more focused on in posterior 3-unit bridge restoration. Many dentists are concerned about various aspects in esthetics, such as morphology of the tooth, value, chroma, hue, translucency, surface texture, etc. But they do not usually consider various methods to restore occlusion. They treat one-tooth-missing area in a similar way in spite of patients having variety of occlusal patterns. Three cases are presented here in 3 or 4-unit bridge restoration. They show some methods to restore patients' occlusal patterns.

A 26-year-old female (Fig. 6) and a 43-year- old male (Fig.
A 32-year-old presented with a chief complaint of restoration of #46 missing area after gantho- surgery. He had iatrogenically slight TMJ prob lem after surgery.
A 32-year-old patient had chief complaint of restoring #46 missing area (Fig. 1). #46 had been extracted 8 weeks before impression-taking because of periodontal problems.
The pantographic tracing was meaningful and reliable although the patient had TMJ problem because the tracing curves were reproducible. The casts were mount ed on the fully adjustable articulator (Denar D-5A, Denar Corp.) (Fig. 18) and the final restoration was made. Minimal occlusal adjustment was done and the restoration was finally cemented (Figs.
성능/효과
in this case. The problem was that it was considerably difficult to adjust occlusion to group function by using this general technique because the semi-adjustable articulator has the gnathologic concept. This point was considered in the next cases.
