Summary
Middle-aged patients with severe overbite and missing molars require comprehensive dental therapy, including orthognathic surgery and prosthodontic treatment, to correct dentofacial deformities and prevent occlusion collapse.
Area of Science:
- Dentistry
- Orthodontics
- Oral Surgery
Background:
- Severe overbite in middle-aged adults can lead to soft tissue trauma due to lack of inter-occlusal space.
- Prosthetic treatment alone is often insufficient without addressing underlying dentofacial deformities.
Purpose of the Study:
- To highlight the importance of comprehensive surgical orthodontic and prosthetic treatment for middle-aged patients with severe overbite and dentofacial deformity.
- To present case studies illustrating successful treatment outcomes.
Main Methods:
- Reported on two middle-aged patients with severe overbite, dentofacial deformity, and missing molars.
- Utilized preoperative orthodontic treatment, implant prostheses for occlusal elevation, and orthognathic surgical procedures (SSRO, Le Fort I osteotomy).
Main Results:
- Both patients had prior prosthetic treatment without occlusion improvement.
- Surgical and prosthetic interventions successfully addressed severe overbite and dentofacial deformities.
Conclusions:
- Malocclusion with dentofacial deformity is a significant risk factor for severe deep overbite and occlusion collapse.
- A combined approach of prosthodontic treatment and comprehensive dental therapy, including orthognathic surgery, is crucial for these patients.
