Item 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 MaríaBackground: 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.Item Clinical performance of tooth root blocks for alveolar ridge reconstruction(International journal of oral and maxillofacial surgery, 2022) Bazal-Bonelli, S; Sánchez-Labrador, L; Cortés Bretón Brinkmann, Jorge; Pérez-González, F; Meniz García, Cristina María; Martínez González, José María; López-Quiles Martínez, JuanThis systematic literature review set out to investigate the clinical outcomes of autogenous tooth root blocks used for ridge augmentation: survival rates, block resorption, implant survival, post-surgical complications, and histology findings. This review followed PRISMA guidelines. An automated search was made in four databases, supplemented by a manual search for relevant articles published before December 2020. The quality of evidence provided was assessed with the Newcastle-Ottawa Quality Assessment Scale and the Joanna Briggs Institute Critical Appraisal tool. Seven articles fulfilled the inclusion criteria and underwent analysis. The articles included a total of 136 patients, who received 118 autogenous tooth root blocks and 26 autogenous bone blocks showing block survival rates of 99.15% and 100%, respectively. Tooth root blocks presented a mean bone gain that was similar to autologous bone blocks but showed less resorption. The implant survival rate was 98.32% for autogenous tooth root blocks. Reconstruction of alveolar crests by means of autogenous tooth root blocks appears to be a satisfactory option for single-tooth gaps and low grades of bone atrophy in terms of the survival of the bone block and the implants placed subsequently. More research providing long-term data is needed to confirm these findings.Item Split bone block technique: 4-month results of a randomised clinical trial comparing clinical and radiographic outcomes between autogenous and xenogeneic cortical plates(Int J Oral Implantol (Berl), 2021) Iglesias Velázquez, Óscar; Tresguerres, Francisco G F; Leco Berrocal, María Isabel; Fernández-Tresguerres Hernández-Gil, Isabel; López-Pintor Muñoz, Rosa María; Carballido, Jorge; López-Quiles Martínez, Juan; Torres García Denche, JesúsPurpose: To evaluate short-term clinical and radiographic outcomes of bone regeneration procedures using thin cortical porcine xenogeneic bone plates in combination with autogenous bone chips compared with thin autogenous cortical plates and autogenous bone chips. Materials and methods: A total of 19 patients (12 women and 7 men, mean age 58.24 ± 3.09 years) were randomly allocated to two different groups regarding surgical procedure: autogenous cortical plates (ACP group) and xenogeneic cortical plates (XCP group). Preoperative CBCT scans were performed for each patient. Surgical time and postoperative pain were recorded, as well as tissue healing and graft resorption after 4 months, then another surgical procedure was performed to place dental implants. Data were analysed using an analysis of covariance. Results: Twenty-one surgical procedures were performed on 19 patients (10 from the XCP group and 9 from the ACP group). The operative time was significantly lower in the XCP group (25.45 ± 3.88 minutes) than in the ACP group (44.10 ± 3.60 minutes). The XCP group also showed less pain, but not significantly less, than the ACP group. The graft resorption rate in the ACP and XCP groups was 2.03 ± 1.58% and 3.49 ± 2.38% respectively, showing no statistically significant difference. Conclusions: Despite the limited sample size and non-uniform distribution between the maxilla and mandible as surgical sites, the results suggest that XCP and ACP grafts are similar in terms of bone volume gain and graft resorption rate, with no significant differences in wound healing or complication rate. Nevertheless, the XCP group recorded lower pain levels and required significantly less operative time compared to the ACP group.Item Analysis of Resorption and Need for Overcorrection in Alveolar Distraction(Int J Oral Maxillofac Implants ., 2016) Reininger, David; Alfredo Rodríguez-Grandjean; López-Quiles Martínez, JuanPurpose: The aim of this study was to evaluate the degree of resorption that occurs following a period of consolidation in alveolar distraction osteogenesis and assess the amount of overcorrection necessary to achieve the planned height. Materials and methods: A retrospective observational study was conducted comprising 19 surgically treated patients, where a total of 19 extraosseous distractors were placed. All patients undergoing surgery had a panoramic radiograph and a computed tomography scan, both at the end of distraction and at the end of the consolidation period. To assess the degree of resorption, the distance from the mandibular border, maxillary sinus floor, or nasal floor to the limit of the crestal bone following consolidation was compared with the height recorded at the end of the distraction period. Results: Resorption occurred in all cases ranging from 7% to 25%. Conclusion: The presence of resorption reported from this study indicates that an overcorrection of at least 20% may be necessary when distraction osteogenesis is performed.Item Application of propolis extract, nanovitamin C and nanovitamin E to prevent alveolar osteitis after impacted lower third molar surgery. A randomized, double-blind, split-mouth, pilot study(Med Oral Patol Oral Cir Bucal, 2021) González Serrano, José; López-Pintor Muñoz, Rosa María; Cecilia-Murga, Roberto; Torres García Denche, Jesús; Hernández Vallejo, Gonzalo; López-Quiles Martínez, JuanBackground: Propolis has anti-inflammatory, analgesic and healing properties. The purpose of this study was to determine whether a gel containing 2% of propolis extract, 0.2% of ascorbic acid and 0.2% of tocopherol acetate is effective in preventing surgical complications related to impacted lower third molar extractions. Material and methods: A randomized, double-blind, split-mouth study was performed. Fifteen patients were recruited who needed bilateral impacted lower third molar extractions with a similar surgical difficulty. A test or placebo gel was administered randomly inside post-extraction sockets. Each patient was instructed to apply the gel 3 times/day in the surgical wound for a week. After a month, the contralateral third molar was extracted, and the opposite gel applied. The following parameters were diagnosed/evaluated and then recorded: alveolar osteitis following Blum's criteria, swelling and trismus at day one, two, three and seven post-intervention, wound healing at day 7 post-intervention, and postoperative pain using a visual analog scale, as well as, the number of analgesic pill intake. Results: A total of twenty-six surgical procedures were performed in 13 patients (mean age 20.67±2 years). Alveolar osteitis was reported in 3 patients from the placebo group (23.1%) and none in the test group (0%) (p=0.25). No statistically significant differences were reported in swelling, trismus, wound healing or analgesic pill consumption between two groups. But statistically lower postoperative pain during the 7 days after surgical extractions was found according to visual analog scale in test group compared to the placebo group (p=0.007). No side effects were reported. Conclusions: The application of this gel may be effective in preventing alveolitis and thus reducing postoperative pain after impacted third molar extractions. More randomized clinical trials with larger sample are needed to confirm these results.Item In vitro comparison of primary stability of two implant designs in D3 bone(Med Oral Patol Oral Cir Bucal, 2017) González Serrano, José; Ortega Aranegui, Ricardo; López-Quiles Martínez, JuanBackground: Primary stability (PS) is a key factor for implant survival rate and depends on implant design or bone quality. The aim of this study was to compare different thread designs implants, evaluating PS with periotest values (PV) and implant stability quotient (ISQ) values through resonance frequency analysis (RFA). Material and methods: A total of 60 implants (Radhex®, Inmet-Garnick S.A., Guadalajara, Spain) were placed in freshly bovine ribs in vitro. Two designs were used: 30 tapered body with single thread design (PHI) and 30 tapered body with double thread design implants (PHIA). Both designs were 4mm wide and 12mm long. Implants were placed according to manufacturer's guidelines. Osstell™ and Periotest® devices were used to evaluate PS by a blinded independent observer. Computed tomographies (CTs) of the ribs were made (BrightSpeed Series CT systems, GE Healthcare, Milwaukee, WI, USA) and bone quality surrounding each implant was evaluated in Hounsfield Units (HU) using Ez3D Plus software (Vatech Co., Korea). Bone quality was classified according to Misch and Kircos in D1, D2, D3 or D4. Results: All implants were mechanically stable. Only implants placed in D3 bone (350-850 HU) were selected for the study: 28 PHI and 26 PHIA. The one way ANOVA showed significant difference (p < 0.005) among two implants designs in ISQ values (61,55 ± 6,67 in PHI and 68,94 ± 5,82 in PHIA). No significant difference (p = 0,171) was shown in PV between two designs (-4,47 ± 1,39 in PHI and -4,77 ± 0,87 in PHIA). Conclusions: Higher PS was found using Osstell™ device in implants with double thread design (PHIA) in comparison to implants with single thread design (PHI) in D3 bone.Item Maxillary sinus balloon lifting and deferred implantation of 50 osseointegrated implants: a prospective, observational, non-controlled study(International Journal of Oral and Maxillofacial Surgery, 2018) López-Quiles Martínez, Juan; Melero-Alarcón, C.; Cano-Durán JA; Sánchez-Martínez-Sauceda EI; Ortega Aranegui, RicardoThe aim of this study was to assess the effectiveness of minimally invasive antral membrane balloon elevation (MIAMBE). Twenty-seven patients with severe resorption of the posterior maxilla were treated by balloon catheter-assisted sinus lift procedure with deferred implant placement. Panoramic radiographs and computed tomography scans were obtained prior to surgery and at 6 months after surgery, before implantation. Data collected following surgery included inflammation, pain, bleeding, infection, and haematoma. Pain and inflammation were recorded using a six-point verbal rating scale (VRS). The patients were followed up for an average of 15 months. The initial sinus floor height was measured for each planned implant and compared with the height at 6 months post-surgery. The average bone height gain was 8.10 ± 3.45 mm (range 0.5–13.95 mm). Inflammation on the VRS ranged from 0 to 3 (mean 0.97 ± 0.85), while pain ranged from 0 to 4 (mean 0.87 ± 1.19). There was a perforation of the Schneiderian membrane smaller than 2 mm in one case. In another case, the balloon lift procedure had to be aborted and changed to the conventional Tatum technique due to breakage of the balloon inside the sinus. The results of this study show the balloon sinus lift technique to be an easy procedure to perform, with apparently low rates of inflammation and pain, and to provide sufficient quantity and quality of bone for the placement of osseointegrated implants.
