Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series

Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series
To measure the buccal plate reconstruction of extraction sockets with labial plate dehiscence defects using a bone allograft in combination with an absorbable collagen membrane and a custom-healing abutment at the time of tooth removal. Implants placed into sockets with labial plate dehiscence defects demonstrated radiographic reformation of the labial plate dehiscence defect at 6 to 9 months post-treatment. The net gain in labial plate on CBCT in L1 and L2 was 3.0 mm, where 0 mm existed at pre-treatment. The minimum amount of labial plate thickness of 2.0 mm was achieved in all treated sites, evaluated radiographically at 6-9 months post-operatively, in a single procedure, without flap elevation and maintaining the gingival architecture and satisfactory esthetics.

Flapless Postextraction Socket Implant Placement, Part 2. The Effects of Bone Grafting and Provisional Restoration on Peri-implant Soft Tissue Height &amp; Thickness - A Retrospective Study

Flapless Postextraction Socket Implant Placement, Part 2. The Effects of Bone Grafting and Provisional Restoration on Peri-implant Soft Tissue Height & Thickness - A Retrospective Study
This article presents the results of evaluating the changes in peri-implant soft tissue dimensions associated with immediate implant placement into anterior post-extraction sockets for four treatment groups: no BGPR(bone graft, no provisional restoration), PR (no bone graft, provisional restoration), BG (bone graft, no provisional restoration), and BGPR (bone graft, provisional restoration). The vertical distance of the peri-implant soft tissue was greater for grafted sites than for non-grafted ones. The facial soft tissue thickness at the gingival third was greater for grafted than for non-grafted sites and for sites with provisional restorations compared to sites without them, respectively. The net gain in soft tissue height and thickness was about 1mm. The increases in vertical and horizontal dimensions for grafted sites were between 0.5 and 1.0mm, as compared to sites with no bone graft and no provisional restoration.

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

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.

Flapless Postextraction Socket Implant Placement in the Esthetic Zone: Part 1. The Effect of Bone Grafting and/or Provisional Restoration on Facial-Palatal Ridge Dimensional Change

Flapless Postextraction Socket Implant Placement in the Esthetic Zone: Part 1. The Effect of Bone Grafting and/or Provisional Restoration on Facial-Palatal Ridge Dimensional Change
The dental literature has reportted vertical soft tissue changes that can occur with immediate implant placement, bone grafting, and provisional restoration ranging from a gain or loss of 1.0mm. However, little is known of the effects of facial-palatal collapse of the ridge due to these clinical procedures. Based upon treatment modalities rendered, an ensuing contour change can occur with significant negative esthetic consequences. The results of a retrospective clinical cohort study evaluating the change in horizontal ridge dimension associated with implant placement in anterior postextraction sockets are presented for four treatment groups. Therefore, it is recommended to place a bone graft and contoured healing abutment or provisional restoration at the time of flapless postextraction socket implant placement.

Two Immediate Temporization Methods Exemplified: Flap vs. Punch Technique in Implant Surgery

Two Immediate Temporization Methods Exemplified: Flap vs. Punch Technique in Implant Surgery
Protocols and techniques for immediate tooth replacement in the esthetic zone have become more popular and predictable within the past decade. Two different clinical scenarios are presented where immediate temporization of implants placed into healed or augmented ridges is exemplified. The benefits of augmentation prior to implant placement and temporization are that flap elevation is not required; therefore, the blood supply to the labial plate is not compromised, thereby eliminating potential midfacial recession. In addition, the soft tissue subgingival shape of the temporary crown can be non-surgically sculpted at the time of implant placement since the patient is already anesthetized.

The Dual-Zone Therapeutic Concept of Managing Immediate Implant Placement and Provisional Restoration in Anterior Extraction Sockets

The Dual-Zone Therapeutic Concept of Managing Immediate Implant Placement and Provisional Restoration in Anterior Extraction Sockets
Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this case enable practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissues coronal to the implant-abutment interface. This approach involves atraumatic tooth removal without flap elevation, and placing a bone graft into the residual gap around an immediate fresh-socket anterior implant with a screw-retained provisional restoration acting as a prosthetic socket seal device.

Maxillary Anterior Papilla Display During Smiling: A Clinical Study of the Interdental Smile Line

Maxillary Anterior Papilla Display During Smiling: A Clinical Study of the Interdental Smile Line
The purpose of this research was to quantify the presence or absence of interdental papillae during maximum smiling in a patient population aged 10 to 89 years. The visual display of interdental papillae during maximum smiling occurred 380 of the 420 patients examined in this study, equivalent to a 91% occurrence rate. Eighty seven percent of all patients categorized as having a low gingival smile line were found to display the interdental papillae upon smiling. Differences were noted for individual age groups according to the decade of life as well as a trend toward decreasing papillary display with increasing age. The importance of interdental papillae display during dynamic smiling should not be left undiagnosed since it is visible in over 91% of older patients and in 87% of patients with a low gingival smile line, representing a common and important esthetic element that needs to be assessed during smile analysis of the patient.

A Biometric Approach To Aesthetic Crown Lengthening: Part 1 - Midfacial Considerations

A Biometric Approach To Aesthetic Crown Lengthening: Part 1 - 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. This article demonstrates a technique using these gauges to objectively determine the correct position of the underlying hard tissues and render predictable, aesthetic treatment.

A Biometric Approach to Predictable Treatment of Clinical Crown Discrepancies

A Biometric Approach to Predictable Treatment of Clinical Crown Discrepancies
Dental professionals have long been guided by mathematical principles when interpreting aesthetic and tooth proportions for their patients. While many acknowledge that such principles are merely launch points for a smile design or reconstructive procedure, their existence appears to indicate practitioners’ desire for predictable, objective, and reproducible means of achieving success in aesthetic dentistry. This article introduces innovative aesthetic measurement gauges as a means of objectively quantifying tooth size discrepancies and enabling the clinician to perform aesthetic restorative dentistry with success and predictability.

Chu&#39;s Aesthetic Gauges: Proportion

Chu's Aesthetic Gauges: Proportion
The Proportion Gauge has the T-bar tip on one end and an In-line tip on the opposite end. The T-bar tip is used on teeth with normal alignment and the In-line tip is used for crooked or crowded teeth where the horizontal arm of the T-bar is obstructed by the rotated teeth. The instrument is used to measure the width and length of maxillary anterior teeth. The tip measurements have a predetermined ratio of about 78% (based on the study results on the average width, length ratio of the maxillary anterior…

Range &amp; Mean Distribution Frequency of Individual Tooth Width of the Maxillary Anterior Dentition

Range & Mean Distribution Frequency of Individual Tooth Width of the Maxillary Anterior Dentition
Proper diagnosis of tooth size for each patient is critical in treatment planning for aesthetic restorative dentistry. The goal of this study was to determine the clinically relevant range and mean distribution frequency of individual tooth width of the maxillary anterior dentition within a given population of patients. Mean values for restoration of tooth size were not interchangeable for the different group size of patients or respective tooth groups. The results of this study suggest that there exists a range value of maxillary anterior tooth width for both males and females. Gender differences are a critical factor in restoring an aesthetically pleasing smile.

Chu&#39;s Aesthetic Guages: Crown Lengthening

Chu's Aesthetic Guages: Crown Lengthening
The Crown Lengthening Gauge has the Biologic Periogauge (BLPG) tip on one end and the Papilla tip on the opposite end. The BLPG tip is used to achieve the propermid-facial clinical crown and biologic crown (osseous crest to incisal edge position) length during surgical crown lengthening procedures. The Papilla tip follows the use of the BLPG tip to establish the correct aesthetic position of the interdental papilla fromthe incisal edge before the flap is closed and sutured.

Restorative Space Management: Treatment Planning &amp; Clinical Considerations for Insufficient Space

Restorative Space Management: Treatment Planning & Clinical Considerations for Insufficient Space
In attempting to provide a restorative solution for cases that have been compromised by spatial considerations, clinicians have traditionally opted for an orthodontic approach that did not provide optimal aesthetics due to changes in tooth morphology, specifically tooth size and shape as a result of dental deterioration. With the advent of contemporary aesthetic materials and preparation techniques, clinicians and technicians are now empowered to deliver a penultimate result with minimal compromise to the surrounding dentition. This article presents the clinical and laboratory considerations that must be addressed when providing a prosthetic restoration for crowded teeth.
