Background: The technique of using bone grafts or different biomaterials for augmentation of the maxillary sinus prior to implant placement is well accepted by clinicians. However, clinical documentation of some bone substitutes is still lacking.
Purpose: This prospective study was designed to evaluate the success rate of implants placed after maxillary sinus augmentation with a novel synthetic biphasic calcium phosphate (BCP) or deproteinized bovine bone (DBB), the latter acting as control.
Material And Methods: Nine edentulous patients and two partially edentulous patients with a mean age of 67 years with a bilateral need for sinus augmentation, < 5 mm residual bone in the floor of the sinus and a crestal width ≥ 4 mm, were included in the study. After bilateral elevation of the Schneiderian membrane, all patients were randomized for augmentation with synthetic BCP in one side and DBB in the contralateral side. After 8 months of graft healing, 62 implants with an SLActive surface were placed. Implant survival, graft resorption, plaque index, bleeding on probing, sulcus bleeding index, probing pocket depth, and implant success rate were evaluated after 1 year of functional loading.
Results: After a mean of 118 days, all patients received their fixed prosthetic constructions. One implant was lost in each biomaterial, giving an overall survival rate of 96.8%. Success rates for implants placed in BCP and DBB were 91.7 and 95.7%, respectively. No significant difference in marginal bone loss was found around implants placed in BCP, DBB, or residual bone, respectively. The mean graft resorption was 0.43 mm (BCP) and 0.29 mm (DBB).
Conclusion: In this limited study, implant success rate was not dependent on the biomaterial used for maxillary sinus augmentation. Similar results were found after 1 year of functional loading for implants placed after sinus augmentation using BCP or DBB.

: Sinus lifting, a procedure to augment bone in the maxilla, may cause complications such as sinusitis due to impaired drainage. This study aimed to assess how sinus lifting impacts airflow in the sinus cavity, which is essential for patients undergoing dental implants. Using computational fluid dynamics (CFD), this research analyzed airflow changes after sinus floor elevation, offering insights into the aerodynamic consequences of the procedure.

Odontogenic keratocysts (OKCs) are an invasive type of odontogenic cyst that rarely occurs in the maxilla. This article presents a case of OKC complicated with ectopic teeth occurring in the maxillary sinus. This article collects a case of a 19-year-old female patient with an ectopic tooth in the maxillary sinus associated with an OKC.

Aim: This study aimed to evaluate the impact of a combination of immediate implant placement with maxillary sinus augmentation (MSA) solely using platelet-rich fibrin (PRF) on guided bone regeneration.
Materials And Methods: An interventional before-after (pre-post) study design was used with 30 dental patients (≥18 years of age; 14 males and 16 females) with initial bone heights ranging between 4 and 6 mm. Following the general check-up and the creation of a study model, the planned implant location demonstrated an external right maxilla diameter of more than 5 mm, thereby validating the cone-beam computed tomography (CBCT) radiograph.

Purpose: This retrospective study aimed to compare extended sinus lift and extramaxilla surgical protocols for restoring severely atrophic maxillae with zygomatic implants (ZIs) and evaluate their clinical effectiveness.
Materials And Methods: The study includes patients who were treated at a dental clinic in Italy from 2012 to 2022. These patients received fixed screw-retained complete dentures supported by either two or four zygomatic implants (ZIs).
