Teeth

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Summary

Complete removable dental prostheses (CRDPs) significantly alter facial morphology. Anthropometric analysis of photographs revealed reproducible changes in perioral and facial indices after CRDP insertion, aiding aesthetic outcome assessment.

Area of Science:

Dentistry
Anthropometry
Facial Aesthetics

Background:

Rehabilitation of edentulous patients with complete removable dental prostheses (CRDPs) requires understanding morphologic changes.
Establishing a physiologic jaw relationship is crucial for CRDP success.
Anthropometric analysis of facial photographs can elucidate these changes.

Purpose of the Study:

To investigate morphologic changes in edentulous patients after CRDP rehabilitation.
To assess the utility of anthropometric indices in evaluating facial changes.
To correlate these changes with the re-establishment of jaw relationships.

Main Methods:

Photographs of 31 edentulous patients were analyzed before and after CRDP insertion.
2232 anthropometric distances were measured.
18 anthropometric indices related to perioral morphology and facial harmony were investigated.

Main Results:

Significant pre- to post-treatment changes were observed in multiple anthropometric indices.
Key indices included intercanthal-mouth width, lip height, vermilion contour, and nose-to-face height ratios.
These changes were reproducible and statistically significant (p<.05).

Conclusions:

Investigated anthropometric indices provide reproducible results concerning increased occlusal vertical dimension.
These indices can aid in assessing, planning, and explaining CRDP effects on facial morphology.
Application of these indices may improve aesthetic outcomes in CRDP rehabilitation.
