Summary
Orthodontic implants offer stable anchorage without affecting tooth position. Palatal implant placement requires understanding the suture palatina mediana
Area of Science:
- Orthodontics
- Implantology
- Anatomy
Background:
- Orthodontic anchorage can be achieved using immobile implants, avoiding reciprocal tooth movement.
- Endosseous implants can be placed in edentulous ridges, mandibular ramus, or palatal bone.
- Successful osseointegration requires adequate bone base, making palatal midline anatomy crucial for anchorage implants.
Purpose of the Study:
- To investigate the anatomical characteristics of the palatal midline region.
- To determine the ossification status of the suture palatina mediana (SPM) across different age groups.
- To provide data for optimizing palatal implant placement in orthodontic treatment.
Main Methods:
- Histologic analysis of trephine bur biopsies from the palatal midline.
- Evaluation of ossification of the suture palatina mediana (SPM).
- Analysis of donor age range from 12 to 53 years.
Main Results:
- Complete ossification of the suture palatina mediana (SPM) is uncommon before age 23.
- The anterior SPM is less frequently ossified compared to the posterior region.
- A more favorable bone bed for osseointegration may exist posterior to the first premolar line.
Conclusions:
- Palatal implants are a viable option for orthodontic anchorage, particularly in adults.
- Knowledge of SPM ossification patterns is essential for successful palatal implant placement.
- Implant positioning should consider the variable ossification of the SPM, favoring posterior regions for better osseointegration potential.
