Which patient is the BEST candidate for implant-supported tooth replacement after orthodontic treatment?
Answer: A 20-year-old whose jaw growth is complete with adequate bone volume
Implants should be placed only after jaw growth is complete (typically 17–18+ years in females, 19–20+ in males) and with adequate bone volume for osseointegration.
The most significant risk of orthodontically moving teeth adjacent to an osseointegrated implant is:
Answer: Tipping of adjacent teeth toward the implant without implant movement
Since osseointegrated implants lack a periodontal ligament, they cannot move orthodontically; adjacent teeth will tip toward the implant if not properly managed.
A patient with a deep traumatic overbite causing palatal soft tissue impingement requires which interdisciplinary approach?
Answer: Orthodontic intrusion and/or overbite correction coordinated with restorative rehabilitation
A traumatic overbite requires orthodontic bite opening (intrusion, extrusion, or repositioning) to relieve tissue impingement before restorations are placed.
Gingival augmentation (connective tissue graft) is recommended before orthodontics in a patient with:
Answer: Very thin keratinized tissue (< 1 mm) at a site where teeth will be moved facially
When the attached gingiva is thin and tooth movement will be directed facially, augmenting keratinized tissue before treatment reduces recession risk.
Ankylosis of a permanent tooth is characterized radiographically by:
Answer: Absence of the periodontal ligament space and direct bone-to-root fusion
Ankylosis results from direct fusion between root cementum and alveolar bone, eliminating the normal periodontal ligament space on the radiograph.
When a congenitally missing upper lateral incisor is managed by space opening for an implant, the canine should ideally be maintained in:
Answer: Class I canine relationship with anterior guidance provided by the future implant crown
Maintaining a Class I canine relationship preserves normal canine guidance, and the properly shaped implant crown can provide the anterior guidance function.
