Spontaneous Growth Induced by a Biologically Oriented V Class Restoration (BOVR) Technique: A 3D Prospective Study

Area of Science:

• Periodontology
• Restorative Dentistry
• Biomaterials

Background:

• Gingival recession (RT1) and non-carious cervical lesions (NCCLs) present functional and esthetic challenges.
• Restoration design, particularly cervical thickness, influences gingival tissue response.
• Understanding soft tissue behavior post-Class V restoration is crucial.

Purpose of the Study:

• To evaluate the impact of tooth shape modification via Class V restorations on gingival tissue response.
• To assess the effect on periodontal health using 3D analysis.
• To correlate restoration thickness with tissue changes.

Main Methods:

• Seven patients with buccal gingival recession and NCCL underwent Class V restorations (BOVR technique).
• 3D analysis of scanned dental impressions monitored tissue profile changes over an average of 4 months.
• Periodontal parameters (probing depth, plaque index, bleeding index) were recorded.

Main Results:

• Increased composite restoration thickness significantly correlated with enhanced tissue thickness and gingival creeping (p ≤ 0.001).
• Periodontal health indicators remained unaffected by the restorations.
• 50% of treated teeth achieved satisfactory outcomes, negating the need for further surgical intervention.

Conclusions:

• Class V restorations that augment cervical thickness can promote significant soft tissue volume gain within 4 months.
• This approach appears safe for periodontal health.
• A 4-month observation period is advisable before considering surgical correction for residual defects.
