Choosing composite resins, based on optical properties alone, in order to mimic the properties of natural tooth structures, does not necessarily provide a satisfactory esthetic outcome. In many instances, failure ensues from incorrect analysis of the optical behaviors of the natural dentition as well as the improper use of restorative materials. Therefore, it is necessary to implement a technique that enables a restorative material to be utilized to its full potential to correctly replicate the natural teeth.

Objective There are multiple treatment options to enhance a patient's smile, from conservative bleaching procedures to composite resins, porcelain veneers, or full‐coverage crowns. Treating patients with porcelain veneers is a commonly used approach in esthetic dentistry. Provisional restorations for veneers can be time‐consuming to make and difficult to retain. This article illustrates a technique for fabricating indirect snap‐on provisional restorations for veneer cases, describing both analog and digital approaches. Clinical considerations The present article presents an alternative provisionalization technique using snap‐on restorations for dental veneers. Application of these techniques will allow for ease of cleansability by the patient leading to healthier soft tissues before the final cementation. Delivery of veneers is more predictable with healthy soft tissue, as bleeding and inflammation may affect the bonding process. Conclusions This technique is an effective provisionalization option in most veneer cases. This approach seems to be well accepted by patients and a good alternative in helping to maintain optimal gingival health with interim restorations before delivery. Clinical significance The use of snap‐on provisionals for veneer restorations will allow the clinician to have an efficient technique with better tissue response before cementation. This prevents inflammation and facilitates a controlled delivery process.

No grupo controle, foi utilizada uma placa de vidro de mesma dimensão. As amostras tiveram a superfície regularizada com lixa d`água (600 e 1200). Após armazenagem a seco no escuro (24 h), foram realizadas as medidas de microdureza Vickers (HMV Shimadzu - 50g/10 segundos). Os dados foram submetidos à Anova fatorial e ao teste de Tukey com nível de significância de 5%.</p></sec><sec><title>Resultado</title><p>O cimento polimerizado apresentou valor médio de microdureza e desvio padrão para o grupo controle de 43,9±1,5 e 43,4±1,3, para as intensidades de 1.000 mW/cm² e 800 mW/cm², respectivamente. O menor valor de microdureza do cimento foi observado para a cerâmica à base de espinélio MgAl₂O₄, polimerizado a 800 mW/cm², com valor de 34,3±3,3.</p></sec><sec><title>Conclusão</title><p>O tipo de cerâmica e a intensidade da fonte de luz influenciam na microdureza do cimento. A intensidade de 1.000 mW/cm² sobre as cerâmicas à base de zircônia e espinélio MgAl₂O₄ resultaram na melhor combinação de valores de dureza do cimento.</p></sec>
