Maximizing tissue response in selected subjects with anterior open bites

Area of Science:

• Orthodontics and Dentofacial Orthopedics
• Periodontal Surgery

Background:

• Anterior open bites present complex orthodontic challenges due to multifactorial etiology and potential instability.
• Effective treatment strategies are needed to enhance tissue response and achieve stable outcomes.

Purpose of the Study:

• To describe a surgical-orthodontic method for maximizing tissue response in treating selected anterior open bite cases.
• To evaluate the efficacy of limited corticotomy in accelerating open bite closure and improving smile esthetics.

Main Methods:

• A cohort of twelve subjects with anterior open bites and inadequate incisor display underwent limited corticotomy.
• The procedure aimed to create an anteroposterior intra-arch anchorage differential to enhance alveolar bone response.
• Cephalometric radiographs were analyzed pre-treatment (T1) and post-treatment (T2), with smile esthetics assessed using a visual analog scale.

Main Results:

• Complete closure of anterior open bites was achieved in an average of six weeks.
• Radiographic analysis confirmed significant maxillary incisor extrusion and retrusion.
• A marked improvement in perceived smile esthetics was observed post-treatment.

Conclusions:

• Limited corticotomy offers a viable and rapid solution for closing anterior open bites in carefully selected patients.
• This approach leads to substantial improvements in smile esthetics, enhancing patient satisfaction.
