Clinical evaluation of direct composite restoration done for midline diastema closure - long-term study

Abstract

Purpose of the Study:The aim of this study was to evaluate clinically the performance of composite resin used to restore midline diastema between the maxillary and mandibular central incisors.Methodology:Direct composite restorations were done for 45 patients with midline diastema between the maxillary and mandibular central incisors. Standard protocols were followed for the placement of composite resin for the diastema closure, and recall visits were made for every 6 months for a period of 60 months for evaluation of the success of these restorations made. Qualified dental personnel examined the restorations made.Results:Clinical evaluations were done after the restorations had been in place for an average of 6 months. Results indicate that none of the restorations were totally lost, and resulting in a 91% overall retention rate for the period of 60 months. About 62% of the restorations made had no noticeable color difference with that of the adjacent tooth, and gingival health indicated 73% of the sample was without any signs of inflammation.Conclusions:Composites restored for diastemas exhibit satisfactory survival rates placed with recommended placement protocols and without occlusal loading.

Direct Midline Diastema Closure with Composite Layering Technique: A One-Year Follow-Up

“…In this case report, one-year recall of a midline diastema closure treatment by using direct composite resins was assessed. Creating a wax-up restoration previously to simulate the diastema closure and building a silicon matrix to guide final composite resin restoration are a common method for this kind of cases [ 8 , 22 ]. However, in this case report, another technique was used without creating a silicon matrix.…”

“…There was no need for using transparent matrix bands or wedges in this technique. This isolation technique allowed us to create two separate restorations having a really close natural alike contact without creating a dark triangle because of not using wedge which are important advantages compared with the silicon matrix technique [ 8 ]. The teeth were restored one by one by layering technique that can also be used in silicon matrix technique [ 13 ].…”

“…Decisions such as the amount of distal proximal reduction, the number of teeth to be treated, the placement and location of prominences and concavities to create the illusion, and the decision for full-veneers or just adding to the interproximal are decided according to that ratio [ 6 ]. The appropriate technique and material for a patient are also based on time, physical, psychological, and economic limitations [ 7 , 8 ]. Direct composite resins in diastema closure cases allow dentist and patient complete control in formation of natural smile [ 9 ].…”

Diastema Closure in Anterior Teeth Using a Posterior Matrix

“…Prabhu et al [26] conducted a study in which midline diastema closure was done in maxillary and mandibular central incisors in a total of 45 patients. Recall visits were made every 6 months for a period of 60 months.…”

Porcelain sectional veneers, an ultra-conservative technique for diastema closure (three-dimensional finite element stress analysis)

“…The first one is closing the diastema by composite resin; this technique may be more conservative for the tooth structure, but it still does not offer the greatest esthetics and the teeth are susceptible to color change overtime. [4][5][6][7][8][9][10][11] The second one -ceramic laminate veneers -offers much better esthetics than composite resin, more durability and resistance to color changes, and is considered a minimally invasive technique, which is regarded as an advantage. [12][13][14][15][16][17] Now we are looking for techniques which might comprise the best of the above-mentioned approaches.…”
