Various approaches to implant placement in the atrophic posterior maxilla are currently advocated in the literature. Such strategies range from the use of block bone graft, to short, tilted, and zygomatic implants, to sinus floor elevation (SFE). SFE has shown to be a predictable surgical procedure to increase bone height in the posterior maxilla. This article provides a narrative overview of SFE techniques, including a modified localized management of sinus floor technique in fresh molar extraction sockets.

A network meta-analysis comparing treatment modalities of short and long implants in the posterior maxilla with insufficient bone height.
BMC Oral Health
December 2024
Department of Stomatology, General Hospital of Northern Theater Command, Shenyang City, 110016, Liaoning, People's Republic of China.
Objective: Based on the critical role of implant length and placement timing in treatment success, this study aimed to compare clinical outcomes (implant failure, marginal bone loss, biological and mechanical complications) between short implants (4-8 mm) versus long implants (≥ 8 mm) with sinus floor elevation, and between delayed versus immediate placement of long implants in the posterior maxilla.
Methods: This network meta-analysis was prospectively registered in the PROSPERO database (CRD42023495027). Adhering to PRISMA-NMA guidelines, we systematically reviewed eligible studies from January 2014 to November 2024 was conducted across major databases, such as the Cochrane Library, PubMed, Embase, Scopus and Web of Science.
Bone Regeneration After Sinus Floor Elevation in an Intact Sinus or a Sinus With Prior Large Membrane Perforation: A Preclinical Study Using a Rabbit Sinus Model.
J Clin Periodontol
December 2024
Department of Periodontology, Kyung Hee University College of Dentistry, Periodontal-Implant Clinical Research Institute, Kyung Hee University Medical Center, Seoul, Republic of Korea.
Aim: To determine bone regeneration following sinus floor elevation (SFE) at sites with or without prior sinus membrane perforation.
Materials And Methods: The sinus membranes in the maxillary sinuses of 12 rabbits were intentionally perforated (≥ 5 mm) on one side, followed by application of a collagen matrix. SFE was performed on both sinuses after 8 weeks of healing, presenting two groups: SFE with a previous large sinus membrane perforation (group SFE_Perf), and in an intact sinus (group SFE).
Analysis of trends in the context of implant therapy in a university surgical specialty clinic: a 20-year retrospective study.
Clin Oral Investig
December 2024
Department of Oral Surgery and Stomatology, School of Dental Medicine, University of Bern, Bern, Switzerland.
Objectives: To analyze the trends in the context of implant therapy in a 3-year patient population and compare it with data obtained over the last 20 years.
Materials And Methods: All adult subjects who received treatment in the context of implant therapy between 2020 and 2022 were included in this retrospective study. Data regarding patient demographics, indications and location of implant therapy, implant characteristics, surgical techniques, complications, and early implant failures were recorded and compared to data obtained in the years 2002-2004, 2008-2010, and 2014-2016.
CGF with Bio-Oss collagen as grafting materials for simultaneous implant placement after osteotome sinus floor elevation: a prospective study.
BMC Oral Health
December 2024
Department of Oral Implantology, Affiliated Hospital of Stomatology, Nanjing Medical University, Nanjing, 210029, PR China.
Background: Osteotome sinus floor elevation (OSFE) procedure with simultaneous implant placement is known to be an efficient procedure in the atrophic maxilla, where bone regeneration is required the most. The purpose of this study was to radiologically evaluate the efficacy of using Bio-Oss Collagen with Concentrated Growth Factor (CGF) as grafting materials for OSFE with simultaneous implant placement in the atrophic maxilla after one year of functional loading.
Methods: A total of 126 implants were placed for 123 patients.

Stomatology Hospital, School of Stomatology, Zhejiang University School of Medicine, Zhejiang Province Clinical Research Center for Oral Diseases, Key Laboratory of Oral Biomedical Research of Zhejiang Province, Cancer Center of Zhejiang University, Engineering Research Center of Oral Biomaterials and Devices of Zhejiang Province, Hangzhou, China.
Objectives: To evaluate the clinical and radiographic results of transalveolar sinus floor elevation (TSFE) with grafting in cases of severely atrophic maxilla.
Materials And Methods: A retrospective analysis of clinical and radiographic data was conducted. Between 2015 and 2018, a total of 105 implants were placed in 105 patients over a follow-up period of 5-8 years.
