PERIODONTAL STABILITY IN SURGICAL CROWN LENGTHENING PREPROSTHETIC INTERVENTIONS -A SYSTEMATIC REVIEW
Abstract:
Statement of the Problem: the periodontal stability after surgical crown lengthening
procedures is an important item for the final prosthetic restoration success. The appropriate time for
healing is still controversial in the specific published literature. Purpose: this review aims at answering
a specific PICO question: what is the optimal time for the final fixed prosthetics procedures, after the
surgical crown lengthening techniques are performed in clinically healthy patients, with good
periodontal condition, to ensure predictable stable periodontal results. Materials and methods: applying
standard selection criteria for studies, detailed search strategies were developed for each database, data
collection was undertaken using specially designed data extraction forms and quality assessment was
done. Results: in the limitations of the review we performed, we believe that the answer to the initial
question can only be a recommendation: in clinically healthy patients with good periodontal condition,
it is recommended a waiting period of 12 months compared to 3 or 6 months, the studies made between
these periods showing a tendency to stabilization of the periodontal structures at all levels. Conclusions:
drawing a conclusion based on scientific data requires the development of standardized studies on this
topic, on a larger period of time.
