Clinical and Esthetical Evaluation of 79 Lithium Disilicate Multilayered Anterior Veneers with a Medium Follow-Up of 3 Years

Abstract

Objectives Primary aim of this study was to evaluate survival rate of lithium disilicate veneers in upper and lower anterior teeth. Secondary aims were to evaluate changing in proportions of teeth before and after restorations and to assess mean thickness of the veneers. Materials and Methods Seventy-nine upper and lower lithium disilicate veneers were made in 13 patients with worn teeth. Mean follow-up was 3 years. To perform anterior definitive rehabilitations, malocclusions and loss of vertical dimension were treated by full mouth rehabilitations to obtain proper occlusal conditions. Veneers were made of lithium disilicate core and fluorapatite-based ceramic stratification. Survival rate was calculated by Kaplan–Meier analysis. Changing in teeth proportion before and after restorations was analyzed by a paired t-test. Descriptive statistics of thickness values were also performed. Results One case of detachment was observed with a 98.7% survival rate. Teeth’s proportions were preserved although the first upper right incisor and canine changed in dimension. Conclusions Lithium disilicate veneers in esthetical rehabilitations of worn teeth proved to be an effective way of treatment in a medium follow-up of 3 years. Proportions seemed to be maintained with a minimum dental removal.

Resin Infiltration in Dental Fluorosis Treatment—1-Year Follow-Up

“…Photographs were taken with D700 (Nikon, Tokyo, Japan) with Nikon AF-D DC 105 mm f/2 lens (Nikon, Tokyo, Japan) and R1C1 dual flash (Nikon, Tokyo, Japan) positioned on a camera tripod at 30 cm from the patient’s teeth. Camera was perpendicularly stabilized to the vestibular surface of the upper central incisors and setting used were the same for the pre- and postoperative pictures (f29, 1/60) [ 22 ].…”

“…Effective measurement of main length of lesions was determined by a digital software elaboration (Rasband, W.S., ImageJ, U. S. National Institutes of Health, Bethesda, Maryland, USA) of photographs [ 22 ] by the same operator. Measurements were taken twice for each lesion with a ten min interval in between.…”

In Vitro Evaluation of Physical and Mechanical Properties of Light-Curing Resin Cement: A Comparative Study

“…14 The performance of resin cement on the luting procedure and their mechanical properties are important factors to consider for the clinical success of indirect restorations. 6,15 Therefore, this study aimed to assess the surface hardness, sorption, solubility, and color stability of light-cured resin cement. The null hypotheses tested were: (1) no difference in microhardness between the evaluated resin cement, (2) no difference in the sorption and solubility between the resin cements tested, and (3) no difference in color stability would be observed between the tested materials.…”

Esthetic Rehabilitation of Anterior Dentition with Different Types of Ceramic Restorations: Two Case Reports

“…Silica-based all-ceramics have been proven effective in numerous clinical studies as an appropriate material for esthetic single tooth restorations. 17,[23][24][25] Ceramic veneers are considered advantageous for maintaining tooth vitality and preserving hard tissues. 26 Full crown preparations require removal of 63 to 72% of tooth structure, while veneers require removal of only 3 to 30% of tooth structure.…”
