Summary
Subapical corticotomy with maxillary transfer can preserve pulp vitality, though some degeneration may occur. Severe atrophy is possible, potentially linked to surgical anemia.
Area of Science:
- Oral surgery
- Histopathology
- Maxillofacial reconstruction
Background:
- Subapical corticotomy is a surgical technique used in orthodontics and maxillofacial surgery.
- Posterior transfer of the maxilla is a procedure to reposition the upper jaw posteriorly.
- Understanding pulpal and radicular tissue response is crucial for surgical success and patient outcomes.
Purpose of the Study:
- To histopathologically evaluate pulpal and radicular changes following combined subapical corticotomy and posterior maxillary transfer.
- To assess the viability of dental tissues after these surgical interventions.
Main Methods:
- Histopathological examination of monkey jaws after the surgical procedures.
- Analysis of pulpal and radicular tissues for signs of degeneration, atrophy, or necrosis.
Main Results:
- Successful surgical procedures generally maintained pulp vitality.
- Slight atrophy and degeneration of pulp tissues were observed in some cases.
- Severe reticular atrophy was noted in certain instances, possibly due to intraoperative anemia.
Conclusions:
- Combined subapical corticotomy and posterior maxillary transfer can be performed with preservation of pulp vitality.
- Careful surgical technique is necessary to minimize risks like intraoperative anemia and subsequent severe tissue degeneration.
- Further research may be warranted to explore preventative measures against operative anemia during these procedures.
