1 Facial Lip, profile, Naso-labial fold.
2 Dental Incisal margin, midline, exposure or smile line.
3 Occlusion Class I
Main objective: Esthetics

To determine the relation between:
1. The proximal end of the implant and
2. The center of the future restored tooth
Goal

Which Came First - The Chicken or the Egg?
Each diagnostic wax up starts with the division of the edentulous
space

Optimal - straight abutments Little or no bone lose.
Borderline - up to 15º angled abutmentModerate bone resorption.
Difficult - 20º and more angled abutmentImportant bone lose.

Evaluation
![Page 11: Implant treatment planning: Model base planning for implant fixed treatment](https://reader035.vdocuments.us/reader035/viewer/2022062405/556ca2d9d8b42a44468b4d04/html5/thumbnails/11.jpg)
Division of the edentulous space is one of the first steps of the planning which determines the location of the future implants.
Light or light-moderate bone lose in the posterior area seldom
requires wax up.
Moderate or Heavy bone lose should be diagnosed with aid of diagnostic wax up to create favorable conditions to restore the esthetics.
The results of the evaluation should determine the necessity of
angled abutments or even bone graft.
