Conditions

Measurement of alveolar ridge buccolingual dimension from a clinical point of view Measurement of the clinical height of the ridge Measurement of soft tissue dimensions.

Interventions

Intervention group: The first intervention group: Ridge restoration material No. 1 (cenobone), the second intervention group: Ridge restoration material No. 2 (matchstic).

Eligibility

Sex/Gender

All

Age

18 Years to 60 Years

Inclusion criteria

Inclusion criteria: The tooth is unmaintainable and a candidate for extraction (due to severe caries, root fracture, failure of root treatment) Age group 18 to 60 years non-smoker The thickness of the buccal wall should be less than 2 mm. All walls are healthy Systemically healthy.

Exclusion criteria

Exclusion criteria: The tooth has a peri apical lesion. Taking drugs that affect bone metabolism like bisphosphonates have a uncontrolled diabetes or high blood pressure the buccal wall have a fenestration or dehiscence pregnancy

Design outcomes

Primary

Measure	Time frame
Reduction of bone and soft tissue resorption. Timepoint: 4months later. Method of measurement: Before tooth extraction, an alginate mold will be taken and a diagnostic cast will be prepared. A template (stent) will be made on the occlusal surface of the candidate tooth and at least one more anterior and posterior tooth on the study cast with self-curing acrylic. This stent allows the measurement of alveolar ridge bone to be repeated at two different times, one immediately after tooth extraction and the other 4 months after keeping silent. Alveolar crest height is measured with a periodontal probe from inside the stent to the middle part of the buccal crest wall. We create an indentation in the stent to guide the same position and angle of entry of the probe when it is used a second time. The buccolingual ridge width is also measured by the periodontal probe from midbuccal/midlabial to midlingual/midpalatal.	—
