This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Application of resorbable membranes for lateral bony window coverage delivers favorable results in sinus floor elevation by increased graft protection. The piezoelectric approach allows repositioning of the sinus bony wall as opposed to rotary window preparation. This may represent a valuable treatment alternative to the placement of collagen membranes for window coverage.Aim/Hypothesis: Our aim was to present the clinical, radiographic and histological results of a prospective, randomized, controlled trial on sinus bony wall repositioning compared to rotary window preparation with membrane coverage.Matrial and methods: 40 patients with at least one missing maxillary premolar/molar were treated by lateral maxillary sinus floor augmentation. Patients were randomized to Test (20 patients): piezoelectric window preparation (NSK VarioSurg3), bony wall repositioning. Control (20 patients) rotary window preparation, resorbable collagen membrane coverage (botiss collprotect). A particulate xenograft (botiss cerabone) was utilized in both groups. Following clinical parameters were registered: duration of surgery, bony window, sinus mucosa preparation; number of sinus perforations; postoperative patient complaints by visual analogue scale (VAS); number of non-steroid inflammatory drugs (NSAID) taken. Qualitative radiographic evaluation was performed on pre- and postoperative CBCT scans. Hard tissues were analyzed histologically in biopsies retrieved at 6months re-entry prior to implant placement (Straumann Tissue Level) by guided surgery (SMART Guide).Results: Duration of surgery was 45u00b111min in test compared to 49u00b111 min in control. Duration of window preparation was 4.45u00b11.36min in test compared to 5.85u00b13.65min in control. Duration of mucosa elevation was 5.8u00b13.3min in test compared to 7.15u00b13.2min in control. Percentage of sinus perforations was 30% in test compared to 35% in control. VAS scores demonstrated lower morbidity in test compared to control: 30.85u00b131.26 vs. 44.5u00b127.07 on the day of surgery, 19.75u00b126.09 /29.40u00b126.6 1 day-, 12.9u00b120,31 / 24.8u00b123.17 2 days-, 9,5u00b116.5 / 17.63u00b121.13 3 days postoperatively. Number of NSAID taken was 1.42u00b10.61 in test compared to 1.75u00b10.91 in control on the day of surgery, 0,89u00b10,94 / 1.15u00b10.93 1 day-, 0.71u00b10.78 / 1.14u00b11,02 2 days-, 0.32u00b10.58 / 0.75u00b10.97 3 days postoperatively. Differences were not significant. Radiographical and histological analysis confirmed favorable hard tissue reconstruction at all sites in both treatment groups. Conclusion and clinical implications: Duration of surgery and window preparation, number of sinus perforations were lower following piezoelectric window preparation and bony wall repositioning with less patient morbidity. Quality and quantity of newly formed hard tissues were comparable to rotary preparation and membrane coverage. Piezoelectric preparation and sinus bony wall repositioning represents a valuable treatment alternative by eliminating the need for membrane application for window coverage in sinus floor elevation.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Lateral bony window coverage utilizing collagen membranes in maxillary sinus floor augmentation by lateral approach delivers favorable results (Pjetursson et al. 2008). The piezoelectric approach allows for repositioning the sinus bony wall (Choung et al.1997), nevertheless data is scarce on the efficacy compared to collagen membrane coverage. The preliminary clinical results of an ongoing prospective, randomized, controlled clinical, radiographical and histological trial are presented. Aims: To demonstrate the non-inferiority of bony wall repositioning compared to collagen membrane coverage in maxillary sinus flooraugmentation. Primary outcome parameter: Histological evaluation. Secondary outcome parameters: duration of surgery and window preparation, perforations, patient morbidity.Materials and methods: 8 healthy patients with at least one missing maxillary premolar or molar with not more than 5mm bone height below the sinus weretreated at the Department of Periodontology, Semmelweis University, Budapest, Hungary by lateral maxillary sinus flooraugmentation. Patients were randomized in two groups: Test (4 patients): lateral sinus window preparation with a piezoelectric device (NSK Variosurg 3), sinus bony wall repositioning. Control (4 patients) lateral sinus window preparation with rotary burs at 400 rpm, bony window covered by resorbable collagen membrane (Botiss Colprotect). Hard tissue grafting was performed using a particulatexenogenic material (Botiss Cerabone) in both groups. Following parameters were registered: duration of surgery and windowpreparation in minutes; percentage of sinus membrane perforations, postoperative patient complaints subjectively evaluated by visual analogue scale, objectively evaluated by number of non-steroid inflammatory drugs taken.Results: Initial healing was uneventful, primary wound healing occurred in all cases, no postoperative infections were observed. Duration of surgery was 50.5u00b19.6 min in test compared to 56.50u00b114.1 min in control. Duration of window preparation was 5.0u00b10.8 min in test compared to 4.8u00b11.7 min in control. Percentage of sinus membrane perforations was 50% in test compared to 50% in control. Postoperative patient complaints subjectively evaluated by visual analogue scale was 24.5u00b130.7 in test compared to 42.3u00b125.6 in control on the day of surgery, 13.5u00b121.4 in test compared to 30.5u00b125.1 in control 1 day postoperatively, 12.5u00b117.7 in test compared to 12.5u00b13.5 in control 2 days postoperatively. Postoperative patient complaints objectively evaluated by number of non-steroid inflammatory drugs taken was 1.5u00b10.6 in test compared to 2u00b10 in control on the day of surgery, 1u00b11.2 in test compared to 0.75u00b10.5 in control 1 day postoperatively, 0u00b10 in test compared to 0.5u00b10.7 in control 2 days postoperatively.Conclusions: According to the preliminary clinical results of the ongoing prospective, randomized, controlled clinical, radiographical and histological trial, duration of surgery, duration of window preparation, percentage of sinus membrane perforations were comparable in test and control. Subjective and objective postoperative complaint evaluation showed more favorable outcomes in the test group, indicating less patient morbidity following piezoelectric sinus window preparation and bony wall repositioning.

Download or read book Quantitative Evaluation of Sinus Floor Elevation Using the Plate Shaped Bone Substitute written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sinus floor elevation is often applied to the molar region of the atrophic maxilla to increase bone mass between the alveolar crest andthe sinus floor. Although autogenous bone graft is, so far, gold standard, limitations of donor site bone volume and post-operativemorbidity could be disadvantages. Thus, artificially synthesized bone substitutes, hydroxyapatite (HA) and tricalcium-phosphate(TCP), might be advantageous useful materials compared to the autogenous bone.We have developed a novel technique of the sinus floor elevation using plate-shaped beta-TCP . In this study, changes of graftedbone volume were quantitatively evaluated with cone-beam computed tomography (CBCT) and image analyzing software before and1, 2, and 5 years after the surgery. Ten cases were recruited in this study. The bony windows were prepared on the lateral wall of the sinus and the sinus membrane wascarefully removed and elevated. Subsequently, the TCP plate was inserted and supported with dental implants or micro-screws.Then, CBCT scan was performed to estimate temporal changes of the bone volume before surgery and at the time points of one, two,and five years after the surgery. Digital Imaging and Communication in Medicine (DICOM) files of CBCT were converted intoStereolithography (STL) files, using dedicated image analysis software for bone volume measurement and superimposing image datawith the best fit method. The difference of the image data representing the bone volume before and after the surgery was amalyzedthree-dimensionally, and the rate of change was calculated. This clinical research was approved by Ethics Committee, School ofDentistry, Iwate Medical University, and the patient's consent was also obtained. Ten cases of the sinus floor elevation with plate-shaped beta-TCPs have been performed since 2011. This study consisted of threemen and seven women. The average age of all the patients was 53.3 years old. Bone volume decreased slightly until 2 years after thesurgery and then increased again until 5 years after the surgery. There had no complications concerning the abnormalities of themaxillary sinus since the postoperative to the present, and it passed well. In most cases, newly formed bone in the sinus wasobserved on X-ray photos 6 month after the operation. The good stability of the dental implant, at the second stage surgery, wasconfirmed. TCP plates remained in the same position and achieved the secure space making for long time. Panoramic X-ray andX-ray CT analyses revealed that TCP-plates were resorbed in 5 years post operation in most cases. The results of our study demonstrated that it is possible to evaluate the change of bone volume of the sinus floor elevationquantitatively using the data of the STL form which converted DICOM. In this clinical trial, a new bone formation was observed in theempty space between the TCP plate and the original sinus floor. TCP is a bone-conductive material and might have accelerated boneformation. This newly established method for sinus floor elevation could bring better long-term prognosis.
