Comparison of Dual Digitally Guided vs Conventional Crown Lengthening
Sponsor: Arab International University
Summary
This randomized controlled clinical trial aims to evaluate the clinical performance and patient-centered outcomes of dual digitally guided crown lengthening compared to the conventional surgical technique in the management of gummy smile caused by altered passive eruption (Type B1). A total of 18 patients will be randomly allocated into two groups: the control group will undergo conventional crown lengthening based on clinical measurements, while the intervention group will receive crown lengthening using a dual digitally fabricated surgical guide. The primary outcome is the gain in clinical crown length at 3 months. Secondary outcomes include operating time, pain perception, patient satisfaction, gingival margin stability, and periodontal clinical parameters. This study aims to determine whether digital guidance improves surgical accuracy, efficiency, and patient satisfaction compared to traditional techniques

Conditions
Interventions
Conventional Crown Lengthening
Conventional surgical crown lengthening performed based on clinical examination and manual measurements. The procedure includes gingival recontouring and osseous resection carried out according to standard periodontal surgical protocols without the use of digital guidance.
Dual Digitally Guided Crown Lengthening
Crown lengthening performed using a dual digitally fabricated surgical guide. The procedure is planned using digital smile design, intraoral scanning, and CBCT imaging to guide both soft tissue and bone resection, enhancing surgical accuracy and predictability.
