Comparison Between Corticocancellous Allograft and Bovine Xenograft for Sinus Augmentation: A Radiographic, Histologic, and Histomorphometric Clinical Study.

Sinus floor augmentation is one of the most common approaches to obtain sufficient bone availability for placing implants in cases with severe bone atrophy in the posterior maxilla. Several bone substitutes are indicated for sinus augmentation, but they may achieve different clinical outcomes. This study aims to compare bovine bone mineral (BBM) with freeze-dried bone allograft (FDBA) in a two-stage lateral window sinus grafting approach.

Palatal bone plate to repair a deficient site in the esthetic zone.

Implants in the esthetic area are challenging for many reasons, all the more so when the hard and soft tissue are deficient at the beginning of the procedure. Numerous grafting techniques are available for the clinician, each one with its own strengths and weaknesses. It is important to understand these differences and to carry out a thorough diagnosis and case selection in order to make the right choice for each patient.

Prevalence of Favorable Anatomy for Palatal Emergence of an Immediate Implant in the Maxillary Central Incisor Post-Extraction Site.

The purpose of this study was to determine the prevalence of favorable anatomy for palatal emergence of an immediate flapless implant in the maxillary central incisor post-extraction site. Implants were virtually placed into maxillary central incisor sites using 3-dimensional implant planning software. Following a strict implant placement criterion to keep a safe distance to the buccal plate and other anatomical structures, sockets were assessed to determine their suitability for an implant emerging from the palatal aspect.

Open flap strategies in socket-shield therapy.

The socket-shield technique shows promising results in the esthetic zone. It is a technically challenging procedure but is effective in maintaining the buccal plate after tooth extraction and avoiding tissue collapse. Therefore, it could be considered a valid option in the immediate implant scenario.

Open flap socket shield in the esthetic zone.

Implants in the esthetic zone can be challenging due to the buccal plate resorption that occurs after tooth extraction. The socket shield technique has proven to maintain the buccal bone and midfacial tissue, minimizing the risk of tissue loss that can lead to an unesthetic emergence of the implant restoration. The socket shield technique is, however, a technically difficult procedure to perform.

Accuracy of mucosa supported guided dental implant surgery.

Implant deviation at platform and apex was comparable to that seen in similar studies, showing that Mucosa Supported Guided Dental Implant Surgery can be a safe implant placement technique. Implant diameter and length, bone density and density deviations showed moderate strong correlation with apical deviation.
