“…Due to this, a powerful light curing system and sufficient irradiation time (40 seconds on each restoration surface) were applied. It might be argued that even slightly subgingival located margins may affect gingival or periodontal health [64] and that therefore subgingival location of margins should be avoided whenever possible.…”

PURPOSE: Evaluating the effect of a proximal margin elevation technique on marginal adaptation of ceramic inlays. METHODS: Class II MOD-cavities were prepared in 40 human molars and randomly distributed to four groups (n = 10). In group EN (positive control) proximal margins were located in enamel, 1 mm above the cementoenamel junction, while 2 mm below in groups DE-1In, DE-2In and DE. The groups DE-1In, DE-2In and DE simulated subgingival location of the cervical margin. In group DE-1In one 3 mm and in group DE-2In two 1.5 mm composite layers (Tetric) were placed for margin elevation of the proximal cavities using Syntac classic as an adhesive. The proximal cavities of group DE remained untreated and served as a negative control. In all groups, ceramic inlays (Cerec 3D) were adhesively inserted. Replicas were taken before and after thermomechanical loading (1.200.000 cycles, 50/5°C, max. load 49 N). Marginal integrity (tooth-composite, composite-inlay) was evaluated with scanning electron microscopy (200×). Percentage of continuous margin (% of total proximal margin length) was compared between groups before and after cycling using ANOVA and Scheffé post-hoc test. RESULTS: After thermomechanical loading, no significant differences were observed between the different groups with respect to the interface composite-inlay and tooth-composite with margins in dentin. The interface tooth-composite in enamel of group EN was significantly better compared to group DE-2In, which was not different to the negative control group DE and DE-1In. CONCLUSION: Margin elevation technique by placement of a composite filling in the proximal box before insertion of a ceramic inlay results in marginal integrities not different from margins of ceramic inlays placed in dentin.

“…Therefore, a correct contour of the restoration is essential for periodontal health. 6,7 Preservation of periodontal health depends, among other factors, on the dental preparation, which must create enough space for the restorative material, 4,8 thus preventing overcontour of the restoration. A prosthetic element with overcontour can cause gingival inflammation, increasing the degree of severity of periodontal illness and promoting loss of supporting bone in the adjacent regions of the surfaces with excess material.…”

Influence of anatomic reference on the buccal contour of prosthetic crowns

et al. 2009

During clinical practice, when performing prosthetic rehabilitation with single crowns, improper reproduction of the dental contour by the dental laboratory is a common occurrence. Therefore, the present study evaluated the fidelity of the reproduction of the buccal contour in an upper left canine performed by three Dental Prosthesis Technicians (DPT) using the indirect laminate veneer technique. First, the DPTs confected the veneers based on a model obtained from the upper arch of a dental dummy, containing a replica of an upper left canine with a prosthetic preparation for a laminate veneer. Then, the same DPTs received other identical models, now with the replica of the upper left canine with no preparation, to be used as an anatomical reference for confecting the laminate veneers. The laminate veneers were then bonded to the plaster models and had their buccal contour individually measured. Measurements were also made of the buccal contour of the reference canine. The data were analyzed by ANOVA and the t-test (p = 0.05). Results showed 100% of buccal overcontour when the laminate veneers were compared to the reference canine, regardless of which DPT confected the veneer and regardless of using or not the anatomical reference. The DPTs who participated in the present study were unable to acomplish a faithful anatomical reproduction of the buccal contour, creating an overcontour in all samples. This situation may be responsible for increasing the probability of periodontal and esthetic harm in clinical practice.

AbstrakJaringan periodontal yang sehat bergantung pada penempatan restorasi yang tepat terutama di bagian proksimal, sedangkan penempatan yang berlebih (overhang) dapat berperan sebagai faktor terjadinya gingivitis dan kehilangan tulang alveolar. Tujuan penelitian untuk mengetahui relasi prevalensi status periodontal dan kehilangan tulang alveolar pada restorasi proksimal. Studi deskriptif potong lintang pada penderita yang berkunjung di Poli Gigi Puskesmas Tarogong kabupaten Garut periode bulan Maret-November 2010 dinilai status periodontal yang meliputi indeks perdarahan gusi menurut The National Institute of Dental Research, kedalaman poket menggunakan probe Williams dengan skala 0-10 mm, indeks plak Silness-Löe dan kehilangan tulang alveolar dengan analisis teknik Schei. Sampel yang didapat sebanyak 21 dari 35 restorasi proksimal overhang mengalami perdarahan gusi pada saat probing. Indeks plak Silness-Löe 8 dari 14 subjek penelitian termasuk dalam kategori buruk dan 6 dari 14 kategori sedang. Restorasi proksimal overhang dengan kedalaman poket di atas 3 mm sebanyak 24 dari 35 restorasi dengan kehilangan tulang alveolar rata-rata sebanyak 8%. Relative risk perdarahan gusi pada restorasi proksimal yang overhang 1,05 sedangkan kedalaman poket adalah 1,60. Simpulan, pada restorasi proksimal overhang didapatkan nilai indeks plak sedang hingga buruk, kedalaman poket lebih dari 3 mm, dan kehilangan tulang alveolar. [MKB. 2012;44(3):133-7].Kata kunci: Kehilangan tulang alveolar, restorasi overhang, status periodontal Periodontal Status and Alveolar Bone Loss on Overhanging Proximal Restorations AbstractA healthy periodontal tissue dependent on placing a proper restoration especially proximal restoration whereas to place an overhang restoration could be a risk factor for gingivitis and alveolar bone loss. The aim of the study was to find out relation prevalence periodontal status and alveolar bone loss on proximal restorations. A descriptive cross-sectional study was conducted on patients who visited Tarogong Dental Unit Public Health Centre, Garut Regency between March and November 2010 and their periodontal status including The National Institute of Dental Research. Gingiva bleeding index, probing pocket depth using Williams probe with scale 0-10 mm, Silness-Löe plaque index and Schei technic alveolar bone loss analysis were recorded. Twenty-one out of thirtyfive of overhanging proximal restorations had bleeding on probing. Based on plaque index (Silness-Löe) 8 out of 14 respondents were categorized as a poor and 6 out of 14 had moderate category of plaque index. Overhanging proximal restorations, which had pocket depth more than 3 mm, were 24 out of 35 restorations with 8% mean alveolar bone loss. Relative risk of gingival bleeding on overhanging proximal restoration was 1.05 meanwhile the relative risk of pocket depth was 1.60. In conclusions, on overhanging proximal restorations show that there are poor plaque index, bleeding gingival, probing pocket depth more than 3 mm and alveolar bone loss. [MKB. 2012;44(3...
