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 and...

Assessment of the Mouth

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Background:

Multiple missing teeth can impair masticatory function and quality of life.
Implant-supported prostheses offer a solution for tooth replacement.
Optimizing occlusion is crucial for effective mastication.

Purpose of the Study:

To evaluate functional improvements after replacing missing teeth with implant-supported crowns.
To assess changes in masticatory timing, movements, and muscle activity.
To determine the impact of Disclusion Time Reduction (DTR) therapy on masticatory function.

Main Methods:

A prospective cohort study involving 30 patients with missing teeth.
Measurements included bite force, EMG activity, and incisor-point movements during chewing (gum and hard food).
Disclusion Time Reduction (DTR) occlusal therapy was applied post-implant placement; data analyzed using Wilcoxon signed-rank and Student's t-tests.

Main Results:

Significant improvements in masticatory parameters were observed for both gum and hard-bolus chewing (P < 0.05).
Average Chewing Pattern (ACP) analysis showed enhanced chewing efficiency.
Reduced disclusion time (P < 0.00000) and EMG muscle activity during lateral excursions (P < 0.000002) were recorded.

Conclusions:

Implant-supported crowns, combined with DTR therapy, significantly enhance masticatory function and muscle activity.
Restoration of missing teeth leads to more normal chewing patterns and reduced muscle effort.
The study demonstrates the efficacy of implant restorations in restoring complex oral functions.
