Minimal Preparation Porcelain Veneers - Using the intraoral composite mock-up to treat orthodontic relapse

Sep 27, 2026

Porcelain veneers are presented as an esthetic restoration for anterior teeth, emphasizing the evolution of adhesive strength, fracture resistance, and marginal adaptation that supports durable outcomes with conservative preparation. The case describes orthodontic relapse causing altered arch form, lingualized axial inclinations, incisal wear, and an overall shade concern. After discussion, a treatment plan uses digital photography, composite mock-up sculpting, prophylaxis, tray whitening, and eight minimal-preparation veneers to achieve a fuller, more youthful, balanced smile without orthodontic retreatment.

Marus, DDS, AAACD O ver the past two decades, porcelain veneershave evolved into the restoration of choice for anterior teeth because they provide the ability to change the shape, color, size, and angulation of teeth with conservative preparation. the development of greater bond strengths to tooth structure and porcelain, combined with increased fracture resistance as well as improved marginal adaptation of ceramic materials, has proven the porcelain veneer to be a durable and esthetic restoration. the minimal change in shade is required and the teeth are in slight lingual version. in this particular case, the patient had adolescent orthodontic treatment with premolar extractions, which resulted ina less than ideal lingually inclined arch form. in addition, the orthodontic relapse resulted in a drifting of the dentition that directly affected the esthetics of the smile. Because orthodontic relapse is a common phenomenon, there are countless dentitions that can benefit from the minimal- or no-preparation veneers when treated in combination with shade change and incisal edge restoration. Patient History pathology present. the occlusion was a bilateral Class 1 molar relationship with no temporomandibular disorder. History of adolescent orthodontic treatment with premolar extractions was revealed and noted. in lateral excursions, canine rise was present. in protrusion, the maxillary central incisors provided the anterior guidance. Posterior disclusion existed in both lateral and protrusive movements. After many years, some orthodontic relapse had occurred. Careful analysis revealed incisal wear on teeth nos. 7 through 10. the right maxillary central incisor was in a slight lingual version secondary to orthodontic relapse. in general, teeth nos. 4, 6 through 11, and 13 revealed a negative axial inclination (Figure 2 and Figure 3) . in addition, the shade of themaxillary central incisors was d2.2 Diagnosis the patient presented with a smile that showed signs of normal wear and orthodontic relapse. Because the general shade was d2 and the dentition displayed lingualized axial inclinations, this case was ideal for minimalpreparation porcelain veneers. After lengthy discussion with the patient, she concluded that she wanted fuller and more youthful and balanced smile (Figure 4) .3,4 Treatment Plan Before commencing treatment, digital photographs were taken and diagnostic study casts were fabricated from alginate impressions. A preliminary intraoral composite mock-up using Venus® diamond and Venus® Flow (Heraeus, porcelain veneer continues to evolve. this evolution has led to the current and popular use of minimal-and nopreparation veneers. Proper patient identification and caseselection is critical in obtaining a natural result when treating the dentition with minimal-preparation veneers. Patients have long welcomed this concept of along-lasting, minimally invasive procedure that favors the preservation of [enamel. it](enamel. it) cannot be overemphasized that case selection is critical in the application of this technique. if a patient is already naturally protrusive or has a bulky dentition, a no-preparation or minimal-preparation may have undesirable results. the ideal scenario is when a RobeRt D.

Poor alignment and discolored and worn teeth were her chief complaints. the patient wanted a fuller, more attractive smile. the patient’s heightened awareness of her dental appearance led her to the author’s practice in search of a conservative smile makeover. she displayed a unique dental esthetics awareness not typically seen in a patient. this acuity was exemplified by her dissatisfaction with the wear an

FAQs

Why are minimal-preparation porcelain veneers considered a preferred option for anterior teeth?

They can conservatively change tooth shape, color, size, and angulation, with improved bonding and ceramic performance that supports durable, esthetic results.

What orthodontic and dental findings supported the diagnosis in this case?

Orthodontic relapse led to lingualized axial inclinations and incisal wear, with the overall shade described as d2, making the case suitable for minimal-preparation veneers.

What treatment steps were included in the plan?

The plan included digital photos and study casts, prophylaxis and hygiene instruction, tray whitening, and placement of eight minimal-preparation porcelain veneers using specified dental materials.
