Cervical margin relocation: case series and new classification system

PURPOSE: The present clinical study aimed toinvestigate the safety and feasibility of cervical marginal relocation (CMR)procedures in cases of deep caries involving supracrestal tissue attachment(STA).

MATERIALS ANDMETHODS: Fifteen patientswere selected from those attending the Studio Ghezzi Dental Clinic, SettimoMilanese, Milan, Italy. After following an oral hygiene program with specificcounseling sessions, the selected patients were included in a periodicsupportive periodontal therapy program. Depending on the treatment theyreceived, the patients were divided into three groups according to a newclassification system: a) Class 1: Nonsurgical CMR; b) Class 2a: Surgical CMR(gingival approach); c) Class 2b: Surgical CMR (osseous approach). The primaryand secondary outcomes were pocket depth (PD) on probing and residual bleedingon probing (BOP) after 1 year.

RESULTS: No differences were found among thethree CMR approaches for PD (overall mean value after 1 year: 2.5 ± 0.64 mm;overall mean value after 5.7 years: 2.3 ± 0.49 mm) or residual BOP (40% of thecases after 1 year).

CONCLUSION: Based on the study results, theauthors can conclude that CMR procedures do not negatively affect theperiodontal health status of patients when the connective compartment of theSTA is not violated.
