“…(3,4) The contact area of the maxillary teeth are relevant for ensuring optimal 'pink aesthetics' for patients with a high smile line (or visible cervical margins). The iconic study by Tarnow et al, (5) which produced the 'mm rule', stated that when the distance from the contact point to the interproximal osseous crest is 5mm or less, there would be a complete fill of the gingival embrasures with interdental papilla. The chance of complete fill is progressively reduced by 50% for each millimeter increase above the 5mm distance.…”

“…Short contact area might result in black triangles, while high proximal contact area might impinge on the gum and cause unpleasant appearance. (5) The location of the ICA has been studied by Suilkowski (6) who stated that the ICA lies between the incisal and gingival embrasures. Stappert et al (7) measured the proximal contact area on master cast from the apical point of the contact area, corresponding to the peak of the interdental papilla, to the incial point of the contact area equivalent to the initiation of the incisal embrasure.…”

“…He concluded that proximal contact area decreased anteroposteriorly between maxillary central incisors to first premolars bilaterally, from 4 to 3 and 2 to1.5 mm, respectively. Tarnow et al (5) and Martegani et al (3) measured the distance between the bone crest and facial aspect of the apical contact area by sounding the soft tissue. Martegani et al (3) reevaluated the results by periapical radiographs.…”

Objectives: To clinically quantify the apico-incisal height of interproximal areas directly in patients' mouths.Methodology: Thirty participants (11 females and 9 males, mean age=26±1.5 years) were recruited into this study. Measurement of interproximal contact areas was carried out directly in patients' mouths using digital caliper (TERENSA, USA) with measuring accuracy of 0.01mm. The interproximal contact areas that were measured are: central incisor to central incisor, central incisor to lateral incisor, lateral incisor to canine, and canine to first premolar on both sides of the jaw. Statistical significance was based on probability values less than 0.05 (p<0.05). Results:The largest contact point was the one present between central incisors and it ranged from 2.9 to 6.5 mm. On the other hand, the contact point between canine and first premolar was the smallest on both sides of the arch and ranged from 0.6 to 2.5 mm. The dimensions of the contact points declined as we move from anterior area backwards. Statistical analysis using t-test showed that there were significant differences between the measurements of interproximal points of each tooth (P<0.05).Conclusions: the apicogingival dimension of the contact point decreased as we moved from anterior to posterior teeth. The contact area between the central incisors was largest and the one between canine and premolar was the smallest. This study is the first to report direct intra-oral clinical measurement of contact points. Clinical evaluation of contact point dimensions using digital caliber is a viable, quick and accurate method to use.

ObjectiveEvaluation of differences in the clinical performance and crestal bone levels between implants restored with single crowns with platform‐matched or platform‐switched abutments after 3 years.Material and MethodsThe study enrolled adult patients missing two or more adjacent teeth in the posterior mandible with natural teeth mesial to the implant site. Randomization followed open‐flap implant insertion and the corresponding matching or switching healing abutments placed at surgery. Conventional loading was made with cemented crowns. Clinical follow‐up took place annually after loading up to 3 years. Bone level changes were measured in standardized radiographs as the variation in crestal bone from one evaluation to the next.ResultsSixty‐three patients with a total of 135 implants (66 platform matching, 69 platform switching) were analysed. From surgery to 36 months, mean bone loss was 0.28 ± 0.56 mm for the platform‐switching group and 0.68 ± 0.64 mm for the platform‐matching group. A statistically significant difference was found between groups (p = 0.002) with an estimate of 0.39 mm (0.15–0.64, 95% CI) in favour of platform switching.ConclusionsAfter 3 years, platform‐switching restorations showed a significant effect in the preservation of marginal bone levels compared to platform‐matching restorations.

The goal of an implant supported reconstruction is to obtain optimal aesthetics and function. In order to achieve this, visualisation of the final restorative reconstruction is necessary prior to beginning treatment. The term 'restorative-driven' treatment planning has been used to identify this process. 1 It requires a team approach of specialists, who can develop a multidisciplinary treatment plan. It starts with an accurate diagnosis, which will lead to a prognosis of each individual tooth and the overall dentition. This information will help the clinician develop the treatment options suitable for tooth replacement. Only when the goals have been defined can the sequence of therapy be established. Working backwards from the wax-up of the final diagnostic model of the proposed treatment assists not only with the management of the complex case, but will help avoid mishaps. 2 Effective communication between the team and the patient is extremely important. Understanding the patient's expectations is key to a successful outcome. Deciding that these expectations are realistic requires a correct diagnosis and an inter-disciplinary treatment plan that is logical. This approach takes time and requires a comprehensive treatment discussion between the team members, and then a thorough case presentation to the patient. 3 Only then will the patient begin to understand the extent of their problem and the options available to reconstruct their mouth.
