Objective. The aim of this study was to determine the average and maximum height of the papilla around maxillary anterior implants in respect of neighboring structures and location of implants. Materials and Methods. 92 dental implants from 63 patients were investigated in this study. Those implants were placed in the anterior maxillary region and had been loaded for a minimum of one year. After receiving written consent, clinical data including the height of interproximal papillae adjacent to the tooth/implant/pontic were obtained through clinical observation. The independent t-test or ANOVA, the regression modeling, and generalized estimating equation (GEE) models were used for statistical analysis ( p < 0.05 ). Results. Papilla height was calculated as 2.8 mm (1–5.5 mm) for implant-tooth sites, 2.6 mm (1–4 mm) in implants beside pontics, and 2.5 mm (1–3.5 mm) for implants adjacent to implants. Despite the lack of a significant difference in the mean papilla height in the studied groups, the maximum values of papilla heights were significantly different. Conclusions. In this study, no significant differences were found in papilla height mean values in relation to neighboring structures or location of implants in the anterior maxilla. However, the maximum values of papilla heights were observed around implants next to natural teeth.

One of the treatment methods in the field of dental prostheses is placing veneers on severely damaged root treated teeth. The holding power of the veneer is one of the important success factors in such treatments, especially when the teeth have short crowns. One of the factors that can affect the strength of the coating on such teeth is cement. In this interventional laboratory study, silver cast alloy coatings were made on 14 identical dies made of Core Max II, and the dies were randomly divided into 3 groups of 10, and in each group, the coatings were made on the die made of Core Max II was cemented with one of zinc phosphate cement (Harward), glass ionomer (Fugi GC) and Panavia (Kurary) F. Based on quantitative analysis, there was a significant difference between three glass ionomer cements, zinc phosphate and Panavia F in terms of setting. An ideal cement should have good mechanical properties to resist functional forces, adhere well to the underlying surface of the coating, and have high stress tolerance. In addition to cement, the type of blind building material and the physical and chemical relationship between adhesive cement and blind building material are also very important.
