OBJECTIVES: This study aimed to evaluate the radiographic and clinical outcomes of patients undergoing sinus membrane elevation via a minimally invasive crestal approach utilizing the dental implant. MATERIAL AND METHODS: Twenty patients having one or more missing posterior teeth were included. The maxillary sinus membrane was elevated using a dental implant via a crestal approach in areas with insufficient residual bone. CBCT scans were used to measure the amount of newly formed bone, implant length inside the sinus, bucco-palatal sinus width, and bone thickness...

Reports of implant fixtures dislocating into the maxillary sinus during sinus graft procedures are well-documented. However, cases of fixtures migrating into the sinus long after placement have yet to be reported. This case report details the surgical extraction of a displaced screw and cement-retained prosthesis, including a fixture and its abutment, from the maxillary sinus after a minimum of 5 years under functional load. The extracted implant was subsequently examined using scanning electron microscopy and energy dispersive x-ray spectroscopy...

PURPOSE: This study aimed to introduce a graftless sinus lifting approach with simultaneous dental implant placement in the alveolus of the posterior maxilla and compare this approach's outcomes in freshly extracted sockets versus healed sockets. MATERIALS AND METHODS: A prospective study was conducted on 60 patients aged between 27 and 59 years old, requiring dental implants in the posterior maxilla, and diagnosed with reduced vertical bone height (30 with freshly extracted sockets (group A) and the remaining 30 with healed sockets (group B)...

PURPOSE: To investigate the effect of lateral sinus floor elevation (LSFE) on sinus membrane (SM) thickness and sinus health in mucosa thickness less and more than 5 mm. MATERIALS AND METHODS: LSFE was performed in a prospective controlled clinical trial on two groups with less than and more than 5 mm (group A & B) SM thickness and followed for 6 months. Using preoperative and 6-month postoperative CBCT and clinical evaluation, SM thickness changes (primary outcome variable), sinus health, augmented bone height, and length (augmentation adequacy), membrane-related variables, and operation time were measured...

PURPOSE: Maxillary molars have low alveolar bone height diameter due to the presence of the maxillary sinus; thus, a sinus lift may be required in some cases. Changes in the volume of bone substitutes can affect the success of implant therapy. Therefore, this study aimed to compare the changes in the volume of two different bone substitutes-one based on carbonate apatite and the other on octacalcium phosphate-used in maxillary sinus floor elevation. METHODS: Nineteen patients and 20 sites requiring maxillary sinus floor elevation were included in the study...

This case study systematically assessed diverse approaches to sinus augmentation in the presence of sinus pathology. Three patients were carefully selected and categorized as pseudocyst (PsC) (type 1), mucous retention cyst (MRC) smaller than 20 mm (type 2), and MRC larger than 20 mm in size (type 3). All patients underwent sinus augmentation procedures, with each case utilizing a unique surgical approach. Spontaneous drainage was performed for the patient with PsC (type 1), followed by uncomplicated sinus augmentation...

Replacement of missing or hopeless teeth in the esthetic zone is one of dentistry's most critical challenges. In the past, multiple surgical procedures have been needed to reconstruct compromised extraction sites. The surgeries have been associated with long healing times and increased morbidity, all the while patients are using either fixed or removable interim restorations. The procedures identified in this paper minimize surgical operating times, healing times, and delays in obtaining definitive restorations by combining multiple surgical procedures in one visit...

Fungus ball is the most common form of non-invasive fungal sinusitis, and maxillary sinus is the most commonly involved site. Maxillary sinus fungus ball (MFB) accounts for a considerable proportion of unilateral maxillary sinusitis. The prevalence of MFB has recently increased; however, its contributing factors are unclear. This study analyzed the association between MFB and dental implants. One hundred one patients who underwent unilateral maxillary sinus surgery were divided into two groups based on surgical biopsy results: unilateral bacterial sinusitis (UBS, n = 45) and MFB (n = 56)...

Maxillary sinus window design is an important factor in sinus augmentation procedures, playing a key role in managing maxillary sinus elevation complications, avoiding the sinus septum, and providing lateral support for the graft material. A less-invasive window design in comparison to conventional maxillary sinus windows was introduced with an "I"-shaped window for single implant placement. However, drawbacks of this window design have included limited instrument accessibility to the anterior sinus and incomplete membrane elevation...

Well-defined, faintly radiopaque lesions are occasionally observed in the antrum of the maxillary sinus in asymptomatic patients during maxillary sinus floor elevation. These lesions are treated as antral pseudocysts (AP) based on the clinical diagnosis in some cases, and maxillary sinus floor elevation is performed without enucleating these lesions. However, further surgery is required after implant placement if the lesion is a mucocele, odontogenic cyst, or tumour. This comprehensive clinical review aimed to identify an appropriate approach for maxillary sinus floor elevation in patients with well-defined, faintly radiopaque lesions in the antrum based on our clinical experience...

AIM: To evaluate the 3- to 8-year outcomes of dental implants placed with lateral sinus floor augmentation (LSFA) and to identify factors affecting implant survival. MATERIALS AND METHODS: This retrospective study was performed by screening all implants placed with LSFA procedures, which were conducted between January 2012 and December 2016. Subantral bone gain (SABG) and apical bone height (ABH) were assessed using panoramic radiographs.

Restoring the maxillary resection defect involving the alveolar process, the hard and soft palate and the paranasal sinuses in terms of phonetics, mastication and deglutition is more challenging, especially with young patients with aesthetic concerns.This case report describes the prosthodontic rehabilitation of a young patient with a unilateral subtotal maxillectomy due to post-COVID-19 mucormycosis. A patient-specific subperiosteal implant was planned to rehabilitate the patient's bony defect. Using postsurgical CT, a customised subperiosteal titanium framework was fabricated by the direct metal laser sintering method using grade IV titanium alloy...

BACKGROUND: The success of dental implants largely depends on the quantity and quality of available bone. Occasionally, it is necessary to perform additional surgical techniques alongside implant placement to increase the available bone volume and ensure the success and survival of treatments. The objective of this study was to evaluate, through cone beam computed tomography, the need for supplementary bone augmentation methods in implant placement. Additionally, the study aimed to assess the frequency of such techniques based on gender, anatomical sectors, and types of bone augmentation procedures...

A maxillary sinus lift procedure is indicated if a dental implant needs to be placed in the posterior maxilla with limited bone available to accommodate a dental implant. Both open and closed sinus lifting procedures are reliable approaches for increasing the bone volume needed to support proper implant positioning. However, these methods can lead to several complications. In addition to the general complications commonly linked to oral surgery, such as swelling or hematoma, the primary complication in open sinus lifting is typically the perforation of the Schneiderian membrane during osteotomy...
