Clinical Report: Skeletal, Dentoalveolar, Dental, and Soft-Tissue Effects Following MARPE Treatment
Overview
This review evaluates the skeletal, dentoalveolar, dental, and soft-tissue effects of miniscrew-assisted rapid palatal expansion (MARPE) in young adults. Findings indicate significant changes in maxillary and zygomatic bone structures, as well as implications for alveolar bone thickness and dental alignment post-treatment.
Background
Miniscrew-assisted rapid palatal expansion (MARPE) is increasingly utilized to address maxillary transverse deficiencies, particularly in young adults. Understanding the treatment's effects on skeletal and dental structures is crucial for optimizing outcomes and minimizing complications. This review synthesizes data from multiple studies to provide a comprehensive overview of MARPE's clinical implications.
Data Highlights
| Study | N | Average Age | Treatment | Conclusions |
|---|---|---|---|---|
| Cantarella, et al | 15 | 17.2 ± 4.2 y.o. | MSE + 4 MT | Significant lateral displacement of maxillary and zygomatic bones. |
| Park, et al | 14 | 20.1 ± 2.4 y.o. | Disyuntor Hyrax + 4 MT | Effective for maxillary transverse deficiency; pyramidal expansion pattern. |
| Lim, et al | 24 | 21.6 ± 3.1 y.o. | Disyuntor Hyrax + 4 MT | Significant increases in dentoalveolar and skeletal measurements. |
| Shin, et al | 31 | 22.52 ± 5.11 y.o. | Disyuntor Hyrax + 4 MT | Age and palatal length negatively correlated with MPS opening. |
| Jesus, et al | 36 | 15–39 y.o. | Disyuntor Hyrax + 4 MT | Uniform increase in nasal cavity width; greater expansion with MARPE. |
Key Findings
- MARPE leads to significant lateral displacement of maxillary and zygomatic bones.
- The treatment exhibits a pyramidal pattern of expansion with varying degrees across skeletal, alveolar, and dental structures.
- Buccal alveolar bone thickness decreases following MARPE, necessitating careful monitoring for potential dehiscence.
- Age and palatal length are significant predictors of midpalatal suture opening success.
- MARPE uniformly increases the width of the nasal cavity, with greater anterior expansion compared to posterior.
Clinical Implications
Orthodontists should consider the significant changes in bone structure and dental alignment associated with MARPE when planning treatment. Monitoring for buccal alveolar bone loss is essential, particularly in patients with pre-existing thin bone. The findings underscore the importance of individualized treatment planning based on patient age and anatomical considerations.
Conclusion
Reiterate the importance of ongoing research and potential long-term effects of MARPE.
