Ridge Preservation Combined With Open Barrier Membrane Technique in Case of Postextractive Oroantral Communication: A Case Series Retrospective Study.

After dental extraction, a physiological phenomenon of reabsorption of the dentoalveolar process is triggered, especially if periradicular lesions are present, which can sometimes be associated with oroantral communication in the upper posterior maxilla. To investigate a minimally invasive approach, 19 patients undergoing tooth extraction in the posterosuperior maxilla were recruited. All cases presented an oroantral communication with a diameter of 2-5 mm after tooth extraction and the alveolar process and, in some cases, with a partial defect of 1 or more bony walls.

Ridge preservation combined with open barrier membrane technique in case of post-extractive oro-antral communication: a case series retrospective study.

After dental extraction a physiological phenomenon of reabsorption of the dentoalveolar process is triggered, especially if periradicular lesions are present, which can sometimes be associated with oro-antral communication in the upper posterior maxilla. With the aim of proposing a minimally invasive approach, 19 patients undergoing tooth extraction in the postero-superior maxilla were recruited. All cases presented an oroantral communication with a diameter of 2-5 mm after tooth extraction and the alveolar process, in some cases, with a partial defect of one or more bony walls.

Factors Influencing Early Marginal Bone Loss around Dental Implants Positioned Subcrestally: A Multicenter Prospective Clinical Study.

Early marginal bone loss (MBL) is a non-infective remodeling process of variable entity occurring within the first year after implant placement. It has a multifactorial etiology, being influenced by both surgical and prosthetic factors. Their impact remains a matter of debate, and controversial information is available, particularly regarding implants placed subcrestally.

One-stage treatment of multiple recessions in the esthetic area with the bilaminar technique: clinical procedures and 24-month follow-up.

The aim of this case report was to treat eight simultaneous recessions that caused an unesthetic smile in a 27-year-old orthodontically treated female patient and to restore the anterior maxillary teeth in the esthetic area. The treatment consisted of bilaminar mucogingival surgery with a palatine graft and a collagen matrix graft (Mucograft, Geistlich). At 24 months, complete root coverage was achieved in all treated sites, with an increase of keratinized tissue (KT), complete resolution of hypersensitivity, and a high level of esthetic satisfaction.

AQP1 expression in human gingiva and its correlation with periodontal and peri-implant tissue alterations.

Aquaporins (AQPs) are a family of hydrophobic integral membrane proteins that function as transmembrane channels and play an important role in tissue homeostasis. Aquaporin-1 (AQP1), in particular, has been reported to be involved in several biological processes including inflammation, angiogenesis, wound healing and others. Periodontitis and peri-implantitis can be defined as inflammatory processes that affect the tissues surrounding a tooth or an osseointegrated implant, respectively.
