Sinus floor elevation and simultaneous implant placement in fresh extraction sockets: a systematic review of clinical data.

Combining different procedures to reduce the number of surgical sessions and patient discomfort in implant placement and sinus floor elevation has been recommended, and evidence supports good outcomes. The aim of this study was to review the results of clinical studies on sinus floor elevation through extraction sockets and simultaneous immediate posterior implant placement. An electronic search was carried out in PubMed, Scopus, and Web of Science to find English articles published in or before August 2020. A manual search was also performed. Titles, abstracts, and the full-text of the retrieved articles were studied. Thirteen studies met our eligibility criteria: 6 retrospective case series, 3 case reports, 2 prospective cohort caseseries, 1 prospective case series, and 1 randomized controlled trial. Overall, 306 implants were placed; 2 studies reported implant survival rates of 91.7% and 98.57%. The others either did not report the survival rate or reported 100% survival. Sinus floor elevation through a fresh extraction socket and simultaneous immediate implant placement appears to be a predictable modality with a high success rate. However, proper case selection and the expertise of the clinician play fundamental roles in the success of such complex procedures.

The Novel Periosteal Flap Stretch Technique: A Predictable Method to Achieve and maintain Primary Closure in Augmentative Procedures.

BACKGROUND: Correct soft tissue management and achieving tension-free primary closure are pre-requisites for the success of bone augmentation procedures. Several techniques have been developed to facilitate a passive soft tissue primary closure. However, the current techniques are highly invasive and require advanced surgical skills. Hence, the present case series report will describe a novel and simple flap management technique. METHODS: The Periosteal Flap Stretch technique was utilized in bone augmentation procedures for four patients who presented with horizontal and vertical alveolar ridge deficiencies in the anterior maxilla, anterior mandible, posterior mandible, and posterior maxilla. This technique is performed using a blunt surgical curette that engages the periosteum of the mucosa below the mucogingival line of the full-thickness flap and stretches the periosteum in a coronal and outward direction, which results in stretching of the flap without the need for vertical or periosteal releasing incisions. RESULTS: Healing was uneventful for four all cases. No membrane exposure, no soft tissue dehiscence, or any other complications were observed during the six-months healing period after the respective bone augmentation procedures of cases. CONCLUSIONS: The Periosteal Flap Stretch technique is a novel and simple technique that facilities achieving passive and predictable primary soft tissue closure.
