    Management of Schneiderian membrane perforations during maxillary sinus floor augmentation with lateral approach in relation to subsequent implant survival rates: a systematic review and metaanalysis
    (International journal of implant dentistry, 2021) Díaz-Olivares, Luis Alfredo; Cortés Bretón Brinkmann, Jorge; Martínez Rodríguez, Natalia; Martínez González, José María; López-Quiles Martínez, Juan; Leco Berrocal, María Isabel; Meniz García, Cristina María
    Background: This systematic review aimed to propose a treatment protocol for repairing intraoperative perforation of the Schneiderian membrane during maxillary sinus floor augmentation (MSFA) procedures with lateral window technique. In turn, to assess subsequent implant survival rates placed below repaired membranes compared with intact membranes and therefore determine whether membrane perforation constitutes a risk factor for implant survival. Material and methods: This review was conducted according to PRISMA guidelines. Two independent reviewers conducted an electronic search for articles published between 2008 and April 30, 2020, in four databases: (1) The National Library of Medicine (MEDLINE/PubMed) via Ovid; (2) Web of Science (WOS); (3) SCOPUS; and (4) Cochrane Central Register of Controlled Trials (CENTRAL); also, a complementary handsearch was carried out. The NewcastleOttawa Quality Assessment Scale was used to assess the quality of evidence in the studies reviewed. Results: Seven articles fulfilled the inclusion criteria and were analyzed. A total of 1598 sinus lift surgeries were included, allowing the placement of 3604 implants. A total of 1115 implants were placed under previously perforated and repaired membranes, obtaining a survival rate of 97.68%, while 2495 implants were placed below sinus membranes that were not damaged during surgery, obtaining a survival rate of 98.88%. The rate of Schneiderian membrane perforation shown in the systematic review was 30.6%. In the articles reviewed, the most widely used technique for repairing perforated membranes was collagen membrane repair. Conclusions: Schneiderian membrane perforation during MFSA procedures with lateral approach is not a risk factor for dental implant survival (p=0.229; RR 0.977; 95% CI 0.941-1.015). The knowledge of the exact size of the membrane perforation is essential for deciding on the right treatment plan.

    Dental considerations in diagnosis of maxillary sinus carcinoma: A patient series of 24 cases
    (The Journal of the American Dental Association: J Am Dent Assoc: JADA, 2018) Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Cortés Bretón Brinkmann, Jorge; Martín Ares, María; Sanz Alonso, Javier; Martínez González, José María
    Background Maxillary sinus carcinoma is a rare entity with an incidence of 0.2% and a low patient survival rate due to the frequency of late diagnosis. Methods In this multicenter, transversal, retrospective, observational study, the authors analyzed patients who had received a diagnosis of maxillary sinus carcinoma, registering their oral symptoms, histologic type, treatment efficacy, and survival rate. Results Maxillary sinus carcinoma was diagnosed in 24 patients (15 men and 9 women), of which 75% were squamous cell carcinomas. All patients had dental mobility, and some had swelling, orosinus fistula, or some dental loss. Mean patient survival rate was 38.83 months. Conclusions A history of pain or swelling of unknown origin, an unexplained widening of periodontal ligament space, or mobility of the teeth should be considered warning signs of maxillary sinus carcinoma. Practical Implications Recognition of oral symptoms by the dentist would help in making an early diagnosis of maxillary sinus carcinoma, improving the patient’s chances of survival and quality of life.

    Analysis of the Radiological Changes of the Sinus Membrane Using Cone Beam Computed Tomography and Its Relationship with Dental Treatments. A Retrospective Study
    (Biology, 2022) Rey-Martínez, María Helena; Ruiz-Sáenz, Pedro Luis; Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Meniz García, Cristina María; Cortés Bretón Brinkmann, Jorge; Suárez-Quintanilla, Juan Antonio; Martínez González, José María
    The aim of this study was to identify the most relevant dental factors and iatrogenic causes in the development of pathological changes to the sinus membrane and to analyse their possible influence on the development of odontogenic sinusitis. A descriptive, observational study was designed, with 276 patients who had been evaluated via cone beam computed tomography, analysing possible sinus thickening factors, such as apical infections, endodontic treatments, periodontitis, radicular cysts and impacted teeth, as well as iatrogenic factors caused by implant treatments or the development of oroantral communications produced during tooth extraction manoeuvres. Among the dental factors, periodontitis (47.1%), apical pathology (23.5%) and endodontic treatments (23.1%) were the predominant causes of sinus membrane thickening that most frequently produced an occupancy between 2 and 10 mm. Regarding the implant treatments, the placement of implants through the floor of the maxillary sinus was the main cause (9.8%), followed by sinus elevation techniques (6.2%). Dental extraction was the first cause of oroantral communication (5.0%), being the procedure that caused the greatest thickening of the sinus membrane. This study highlights the importance of dental treatments and iatrogenic factors in sinus pathology, and the need for diagnostic interrelations between the different specialists who address this pathology.

    Calcium phosphate modified with silicon vs. bovine hydroxyapatite for alveolar ridge preservation: Densitometric evaluation, morphological changes and histomorphometric study
    (Materials (Basel, Switzerland), 2021) Cadenas-Vacas, Guillermo; Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Sánchez-Labrador, Luis; Cortés Bretón Brinkmann, Jorge; Meniz García, Cristina María; Martínez-González, José María
    After tooth extraction, the alveolar bone undergoes a physiological resorption that may compromise the future placement of the implant in its ideal position. This study evaluated bone density, morphological changes, and histomorphometric results undergone by alveolar bone after applying a new biomaterial composed of calcium phosphate modified with silicon (CAPO-Si) compared with hydroxyapatite of bovine origin (BHA). Alveolar ridge preservation (ARP) was performed in 24 alveoli, divided into a test group filled with CAPO-Si and a control group filled with BHA. Three months later, the mineral bone density obtained by the biomaterials, horizontal and vertical bone loss, the degree of alveolar corticalization, and histomorphometric results were evaluated. Both biomaterials presented similar behavior in terms of densitometric results, vertical bone loss, and degree of alveolar corticalization. Alveoli treated with CAPO-Si showed less horizontal bone loss in comparison with alveoli treated with BHA (0.99 ± 0.2 mm vs. 1.3 ± 0.3 mm), with statistically significant difference (p = 0.017). Histomorphometric results showed greater bone neoformation in the test group than the control group (23 ± 15% vs. 11 ± 7%) (p = 0.039) and less residual biomaterial (5 ± 10% vs. 17 ± 13%) (p = 0.043) with statistically significant differences. In conclusion, the ARP technique obtains better results with CAPO-Si than with BHA.
