Layperson's Esthetic Preference to the Presence or Absence of the Interdental Papillae in the Low Smile Line: A Web-based Study.

Purpose: To determine the layperson's esthetic preference to the visual display (presence) or lack thereof (absence) of the interdental papillae during minimum smiling or the low smile line patient type.

Materials And Methods: Two hundred lay-people were shown three-paired smile images indicative of a low gingival smile line patient type in which the vermillion border of the maxillary lip covered the mid-facial gingiva of the anterior teeth. The three images differed only with respect to [1] presence of interdental papillae, [2] absence of the interdental papilla ("black triangle"), or [3] absence of the interdental papillae (replaced with a long restorative contact area).

Subclassification and Clinical Management of Extraction Sockets with Labial Dentoalveolar Dehiscence Defects.

Immediate implant therapy involving implants placed into intact Type 1 extraction sockets has become a consistent clinical technique. The classification of Type 2 extraction sockets, where the mucosal tissues are present but there is a midfacial osseous dehiscence defect, has been described according to the extent of the buccal bone plate absence. The literature has offered different techniques in the treatment of Type 2 sockets; however, the extent of the defect has never been defined or delineated.

A novel prosthetic device and method for guided tissue preservation of immediate postextraction socket implants.

Preservation of the surrounding hard and soft tissues associated with an immediate postextraction socket implant to replace a nonrestorable tooth in the esthetic zone is one of the greatest challenges facing the dental team. Several studies have documented the biologic and esthetic benefits of bone graft containment with either a custom healing abutment or provisional restoration. Use of a prefabricated shell that replicates the extracted tooth at the cervical region can help achieve guided tissue preservation and sustainable esthetic outcomes in an easy, simple, consistent, and less time consuming way.

Maxillary anterior papilla display during smiling: a clinical study of the interdental smile line.

The purpose of this research was to quantify the visual display (presence) or lack of display (absence) of interdental papillae during maximum smiling in a patient population aged 10 to 89 years. Four hundred twenty digital single-lens reflex photographs of patients were taken and examined for the visual display of interdental papillae between the maxillary anterior teeth during maximum smiling. Three digital photographs were taken per patient from the frontal, right frontal-lateral, and left frontal-lateral views.

A biometric approach to aesthetic crown lengthening: part II--interdental considerations.

Optimizing the aesthetic outcome for patients requiring periodontal aesthetic restorative treatment has become a primary objective in contemporary dentistry. Techniques that simplify and enhance quality of treatment provide substantial benefits to patients and clinicians. This article describes new concepts associated with interdental changes due to alterations in tooth and contact area position, and addresses the need for treatment of the interdental papillae.

A biometric approach to aesthetic crown lengthening: part I--midfacial considerations.

Although human dental anatomy is taught in university curricula, clinicians often witness restorations that are not proportional to one another. Dental restorations should also be proportional to periodontal supporting tissues as an essential aspect of dental anatomy. Measurements can be performed directly on a patient's teeth with aesthetic gauges used to confirm the correct position of the supporting osseous topography.

A prospective clinical patient study evaluating the effect of increasing anesthetic volume on inferior alveolar nerve block success rate.

Objective: The purpose of this study was to clinically evaluate an anesthetic technique in which a second cartridge was reloaded in a traditional dental syringe and reinjected at the same site in regard to success rate of the attempted inferior alveolar nerve block. During the same appointment, a computer-controlled delivery system was used on the opposite side of the same patient to administer 2 cartridges as well. Successful anesthesia and time efficiency of the traditional syringe and computer-controlled technique were then evaluated and compared.

Single-tooth anesthesia: pressure-sensing technology provides innovative advancement in the field of dental local anesthesia.

This article will review standard techniques for intraligamentary injection and describe the technology and technique behind a new single-tooth anesthesia system. This system and technique represents a technological advancement and a greater understanding of intraligamentary anesthesia.

Interstitial tissue pressure associated with dental injections: a clinical study.

Objectives: The purpose was to measure the interstitial fluid pressure generated from tissue resistance during administration of local anesthetic solution at 4 anatomic locations within the oral cavity and to determine whether differences in soft tissue density affect interstitial fluid pressure when anesthetic solution is administered at a fixed flow rate.

Method And Materials: A computer-controlled local anesthetic delivery device (CompuFlo, Milestone Scientific) that records and stores pressure data during a subcutaneous injection was used. Subjects consisted of adult patients seeking routine dental care that required local anesthesia.
