Diode Laser Photocoagulation With Immediate Implant Placement

Placement of an immediate implant is becoming popular because of its potential in minimizing the treatment time and enhancing the patient comfort and esthetic outcomes. It is crucial to maintain adequate thickness of labial bone with the establishment of a stable and healthy gingival seal around the implant abutment to prevent the invasion of bacteria and peri-implant inflammation. Diode lasers have been developed as a promising tool in dentistry, providing a precise manipulation and photocoagulation effect that may have a positive influence on both bone remodeling and soft tissue healing. This study aims to evaluate the effectiveness of the utilization of diode laser photocoagulation with immediate implant placement and customized healing abutment in the maxillary esthetic zone.

Effect of Two Incision Techniques on Soft and Hard Tissue Outcomes in Immediate Implant Placement in Class II Extraction Sockets of the Esthetic Zone:

This randomized controlled clinical trial investigates the effect of two different surgical approaches-Vestibular Socket Therapy (VST) and Flap Elevation Technique-on soft and hard tissue outcomes during immediate implant placement in Class II extraction sockets of the anterior maxilla (esthetic zone). The study enrolled 26 systemically healthy adult patients contributing a total of 48 surgical sites. Each site was randomly assigned to one of the two treatment groups. The VST group employed a minimally invasive vestibular incision to allow atraumatic extraction, implant placement, bone grafting, and membrane placement while preserving the labial soft tissue and periosteal blood supply. The Flap Elevation group followed a conventional intrasulcular flap approach. In both groups, implants were placed with 30 Ncm torque and augmented with MegaOss™ allograft and a resorbable collagen membrane (T-barrier™). Clinical and radiographic evaluations were conducted at baseline, 6 months, and 12 months post-loading. Outcomes measured included Pink Esthetic Score (PES), peri-implant probing depth (PD), mucosal level changes, and crestal bone level changes.

Modified Periosteal Inhibition with Simultaneous Implant Placement in Aesthetic Zone

A randomized controlled clinical and radiographic trial. Twenty sites with remaining roots or non-restorable teeth in the maxillary anterior region that fulfill the inclusion criteria will be selected from the Periodontology Clinic, Faculty of Dentistry, Tanta University. These sites will be divided into two groups; each of which has ten surgical sites. After phase I therapy, a traumatic extraction of the hopeless tooth will be made trying as much as possible to preserve the labial plate of bone and overlying soft tissue. * Once the tooth is extracted, the socket is gently debrided and irrigated using sterile saline solution. Then the dental implant is placed in the best prosthetic driven position, following the guidelines for immediate implants using prefabricated computer guided surgical template. * After accurate implant placement, a full-thickness flap will be elevated at mesial and distal papilla making a buccal envelope. A bone lamina 0.5 mm thickness will be trimmed and hydrated in sterile saline solution for 30 s to soften it; it should be 1-2 mm larger and deeper than the vestibular bone.

Dimensional Changes of Peri-implant Tissue in Immediate Implants With Individualized Healing Abutments

The loss of a tooth leads to a series of biological changes in the tissues, resulting in bone resorption and gingival collapse. To avoid these problems, it has been proposed to place immediate post-extraction implants, allowing a reduction in treatment time and the number of surgeries, as well as better maintenance of the tissues. This technique can be performed with standard abutments after implant placement or, more recently, the use of temporary abutments has been proposed.
