Maxillary sinus grafting is a commonly used treatment alternative in cases with insufficient bone height to enable insertion of implants in the posterior maxilla. It is commonly carried out with autogenous grafts, biomaterials or both. Autogenous bone grafts are considered gold standard for this procedure; however, due to donor site morbidity, it is not as commonly used as other biomaterials. Mandibular tori are hyperostoses on the lingual side of the mandible in the premolar region. This a case in which mandibular tori were used for a sinus augmentation procedure. The patient was then followed up for 2 years with no complaints, or objective symptoms.

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.
Effects of Platelet-Rich Fibrin on Bone Healing Around Implants Placed in Maxillary Sinuses: A Histomorphometric Assessment in Rabbits.

Department of Oral Diagnosis, Division of Oral and Maxillofacial Surgery, Piracicaba Dental School, University of Campinas (UNICAMP), Piracicaba 13414-903, SP, Brazil.
This study investigated the effect of platelet-rich fibrin (PRF) on bone healing around implants placed in elevated sinus cavities. Forty New Zealand albino rabbits were divided into eight groups, based on the time of sacrifice (14 or 40 days) and the material used: blood clot (control), hydroxyapatite (HA) from bovine bone, HA combined with PRF, and PRF alone. Each group consisted of five animals (n = 5).

Background: A comprehensive investigation to associate the use of polynucleotides and hyaluronic acid with bovine bone in maxillary sinus lift procedures in rabbits has not been performed yet. The aim was to evaluate the influence of this novel association on the processes of bone regeneration in maxillary sinus augmentation.
Methods: In this prospective, randomized, within-animal model, maxillary sinus augmentation was performed bilaterally in 12 rabbits.
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).
Heterotaxy Syndrome Diagnosed in an Adult.

Department of Internal Medicine, Sultan 2. Abdul Hamid Khan Educational and Research Hospital, Istanbul, Turkey.
Heterotaxy syndrome, a condition in which the internal organs are abnormally arranged in the thorax or abdomen, is generally diagnosed early in life, often during the neonatal period. We present the case of a 42-year-old male who was incidentally diagnosed with polysplenia syndrome and subsequently diagnosed with heterotaxy syndrome. Upon further investigation, he was determined to have a sinus venosus type atrial septal defect.
