Alveolar Bone Dehiscence and Fenestration Following Accelerated Maxillary Canine Retraction

Not Applicable

Recruiting

• Conditions: Dehiscence; Fenestration

• Registration Number: NCT06500559
• Lead Sponsor: Tanta University

Brief Summary

Alveolar bone loss and fenestration are the most prevalent bone defects that often result in root exposure, gingival recession, and potential treatment relapse or failure. These issues present complications in orthodontic therapy. Hence, reducing the length of orthodontic therapy and minimizing the occurrence of these serious complications are highly important for orthodontic patients, particularly adults. platelet-rich plasma (PRP) injection and decortication are two promising methods for accelerated tooth movements. Thus, The aim of this study is to evaluate alveolar bone dehiscence and fenestrations after canine retraction, using alveolar decortication and PRP injection as two methods for accelerating tooth movements.

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 60

Inclusion Criteria

1. Age of the patients ranged from 16: 22 years old.
2. Malocclusion that requires extraction of the maxillary first premolar and canine retraction (e.g. class I bimaxillary dentoalveolar protrusion and class II div 1 malocclusion).
3. Maximum anchorage needed for the maxillary arch as a part of the orthodontic treatment plan.
4. Good oral hygiene and periodontal condition.

Exclusion Criteria

1. Medically compromised patients.
2. Severe crowding in the maxillary arch.
3. Chronic intake of NSAIDs or any medication that interfere with OTM.
4. Previous orthodontic treatment.

Primary Outcome Measures

Name	Time	Method
Alveolar bone dehiscence	4 months	Pre- and post- retraction CBCTs will be obtained from patients. Linear measurement (mm) for dehiscence (LM-D) will be defined as the distance between the alveolar crest to the cementoenamel junction of each root (critical point will be set at 2 mm)
Alveolar bone fenestration	4 months	Pre- and post- retraction CBCTs will be obtained from patients. Linear measurement (mm) for fenestration (LM-F) will be recorded when the defect involved only the apical one-third of a root (critical point will be set at 2.2 mm)
