Norland and Tarnow classification of gingival embrasures. Depending on the type of the gingival embrasure the type of interdental aid to be used is determined - For teeth with normal embra-sures it is advisable to use thin floss.
For Class I embrasures a thick floss is recommended. For Class II embrasures an Interdental brush. Embrasures between the mandibular central incisors were measured and classified into three types.
Papilla filling pinpoint and BT. Age at the first consultation length of active treatment and maximum crown width were larger in the BT group than in the normal group. The incidence of open gingival embrasures between the central incisors was 22 and 36 in the maxilla and the mandible respectively.
Lingual movement of the incisors distance from the contact point to the alveolar crest after treatment antero-posterior overlap of the two central incisors before treatment in the maxilla and distance. If the centrals are significantly coronal to the canines then the teeth erupted as they wore away. This results in a normal-looking papilla and gingival scallop but a short contact.
Two solutions exist for this. One is to orthodontically intrude the incisors. This will move the papilla and free gingival margins back to their original position.
Papilla and open gingival embrasures. Figure 3 The final restorations were created to close the open embrasures but this results in long contacts and square teeth. 20 Advanced Esthetics Interdisciplinary Dentistry Vol.

Proliferation dental implant interimplant implant design epithelium mucosa keratinized tissue. After 3 categoriesnormal gingival embrasure open gingival embrasure and diastemahad been reliably established the prevalence of open gingival embrasures in the patient sample was calculated.
The subsample of patients with open or normal gingival embrasures was identified and the pretreatment and posttreatment measurements were performed. Interdental Tip Rubber Tip Stimulator Primarily utilized for gingival massage Possibly increase gingival circulation Keratinization and epithelial thickening-Effective removal of biofilm 8 Can be used to remove plaque and debris from exposed furcation areas open embrasures and along gingival. The authors reviewed a total of 51 articles including review of the literature using the terms black triangle.
Interdental papilla and interproximal. Open gingival embrasures also known as black triangles refer to empty space below the interproximal contact when the space is not filled with gingiva. 12 They cause not only esthetic but also periodontal problems related to chronic food retention.
1 Despite the high esthetic demands of adult orthodontic patients previous studies reported a relatively high incidence of 38 to 437 of open gingival embrasures.
