Dental-gingival remodeling with BOPT no-prep veneers

Abstract

Recent years have seen increasing demand for treatments aimed at improving dental esthetics. In this context, both patients and dentists prefer to preserve dental structures as far as possible; thanks to technological advances, especially in adhesive dentistry, new materials and minimally invasive techniques such as “no-prep” (no preparation) veneers have made this possible. Nevertheless, no-prep veneers have specific indications and suffer certain disadvantages. Objectives: This clinical case describes the rehabilitation of the upper anterior region by means of no-prep veneers, with BOPT (Biologically Oriented Preparation Technique) cervical margins. The patient had requested an aesthetic treatment to improve irregularities of the gingival margins associated with the presence of diastemata resulting from microdontia. Key words:BOPT, micro-veneers, hybrid ceramic, ultra-fine veneers, diastemata, without prosthetic finish line, no-prep.

Ceramic veneers on central incisors without finish line using bopt in a case with gingival asymmetry

“…11,12). At the one-year follow-up visit, the soft tissues had stabilized correctly, and good gingival health was observed despite the correction of gingival asymmetry (5-8) (Fig. 13).…”

“…Compared with conventional preparation techniques, BOPT is accompanied by greater gingival thickening produced during dental preparation. This reduces the risk of gingival displacement thanks to increased vascularization, regardless of whether the patient presents a thin or thick gingival biotype (5-8).…”

“…Another disadvantage is related to cementation, as it is not possible to isolate the area precisely as there is no horizontal preparation margin that can be followed, and any excess cement will be difficult to eliminate (6,7). Although the clinical results of BOPT have been promising (5-8), there is not yet sufficient scientific evidence to back its long term prognosis, mainly due to its recent appearance (BOPT was first described in 2013) (5).…”

“…As an alternative to conventional treatment, the use of Biologically Oriented Preparation Technique (BOPT) for applying ceramic veneers in the anterior regions facilitates periodontal tissue management and symmetry. Teeth are prepared without a horizontal finish line, which produces a correct emergence, good adaptation and stabilization of soft tissues, and can even correct soft tissue anomalies and asymmetries (5-8).…”

Evaluation of the fracture strength of porcelain sectional veneers made from different sintered feldspathic porcelains: An in vitro study

“…1,2 Progress in adhesive technologies has led to a variety of more conservative restoration techniques. For example, ultra-thin veneers with minimal or no preparation (no-prep), [3][4][5][6][7] and recently porcelain sectional veneers, which are ultra-thin pieces that partially cover the teeth, and can be etched and adhered to the enamel to restore only the defected area while being ultra-conservative. These restorations can have biologically healthy and optically beautiful margins and emergence profiles if properly selected and managed to avoid overcontouring.…”
