Summary

Molar-incisor hypomineralization (MIH) frequently affects permanent first molars and increases the risk of rapid post-eruptive breakdown and restorative failure. Stainless steel crowns (SSCs) are considered a reliable treatment option for severely affected molars; however, SSC placement may temporarily alter the occlusal vertical dimension and occlusal contacts. Quantitative evidence describing the occlusal adaptation process following SSC placement in MIH-affected permanent molars is limited.

This prospective longitudinal clinical study aims to evaluate occlusal adaptation after SSC placement using the modified Hall technique in MIH-affected permanent first molars. Forty-six children will be included. Intraoral scans will be obtained at baseline, immediately after treatment, and during follow-up visits up to 3 months. Digital models will be superimposed to measure three-dimensional changes in cusp position, occluso-vertical dimension, and occlusal contact area. Temporomandibular joint function and periodontal parameters will also be assessed. The results are expected to provide quantitative evidence on occlusal adaptation following SSC treatment in MIH-affected molars.

Interventions

PROCEDURE

Modified Hall Technique

A preformed SSC will be placed on the selected MIH-affected first permanent molar using the modified Hall technique. The procedure will involve selective caries removal while maintaining a minimally invasive approach and avoiding conventional tooth preparation. Local anesthesia will be administered only when clinically indicated. Digital Scan and Bite Registration Schedule * T0 (Baseline): Immediately before crown placement * T1 (Immediate): Immediately after crown placement * T2 (Two Weeks): Two weeks after crown placement * T3 (One Month): One month after crown placement * T4 (Three Months): Three months after crown placement. At each time point (T0-T4), digital scans of both the maxillary and mandibular arches will be obtained, and a buccal bite registration will be recorded. In addition, temporomandibular joint examination and periodontal evaluation of the tissues surrounding the crowned tooth will be performed at T0, T2, T3, and T4 follow-up visits.
