Sinuslift

OBJECTIVE: The aim the studi. Differential diagnosis of retention cysts of the maxillary sinus with odontogenic cysts, acute and chronic sinusitis, aspergillosis, and mucocele in preparation for sinus-lifting surgery. MATERIAL AND METHODS: The analysis of the case histories of 265 patients aged 18-65 years of both sexes who were treated at the dental clinic «Rudenta Family» from 2016 to 2021 was carried out. On the basis of clinical symptoms and data of cone-beam computed tomography (CBCT), a description of the pathologies of HPV is given for the purpose of differential diagnosis and correct interdisciplinary interaction with ENT doctors for the purpose of dental implantation in the lateral parts of the upper jaw...

Összefoglaló. Az utóbbi időben egyre gyakoribbá vált fogászati implantáció egyik nem kívánt szövődménye az arcüregbe került implantátum, amely a maxilla molaris, esetenként praemolaris régiójának implantációjakor fordulhat elő. Ennek oka lehet a kúpsugaras komputertomográfia nélküli, azaz nem megfelelő tervezés, fennálló arcüreggyulladás és -ventilációs probléma, kevés, puha csont, a fúrási vagy implantátumbehelyezési sebészi gyakorlat hiánya, észre nem vett membránperforáció arcüreg-csontfeltöltés esetén...

Purpose: Maxillary sinus augmentation using the lateral bone window approach has been well documented and studied, with the advent of many newer techniques and instruments. It is prudent that operators make a choice based on scientific evidence and feasibility guided by each case. The purpose of this study is to analyze whether a combination of more than one method could prove beneficial when compared to any one method alone. Materials and Methods: Radiographic and clinical data from 48 augmented maxillary sinuses in 42 male and female patients was collected and the clinical outcome analyzed based on different clinical parameters...

BACKGROUND: Sinuslift is meanwhile an established method of bone augmentation in the posterior maxilla. Aim of the study was to evaluate the significance of intraoperative Schneiderian membrane perforations during maxillary sinus floor elevation surgery using autogenous bone harvested from two different donor sites using a Safescraper device on the success rate, graft survival and implant integration. METHODS: The investigators conducted a retrospective cohort study at the Department of Oral and Maxillofacial Surgery of Military Hospital Ulm composed of patients with severe maxillary atrophy who underwent sinus augmentation from January 2011 until December 2011...

The implant-supported prosthetic rehabilitation of the posterior maxilla may require sinus-grafting procedures due to poor quality and low volume of bone. This can be accomplished using a "lateral window" sinus augmentation or with an osteotome sinus floor elevation (OSFE). The hydrodynamic ultrasonic cavitational sinus lift (HUCSL) (Intralift) is derived from the osteotome technique and allows the reduction of some of the traumatic effects of the osteotome technique. The aim of this study was to compare OSFE and the HUCSL procedures on fresh human cadaver heads...

Implant-Insertion-Torque-Value (ITV) proved to be a significant clinical parameter to predict long term implant success-rates and to decide upon immediate loading. The study evaluated ITVs, when four different and commonly used biomaterials were used in sinuslift-procedures compared to natural subantral bone in two-stage-implant-procedures. The tHUCSL-INTRALIFT-method was chosen for sinuslifting in 155 sinuslift-sites for its minimal invasive transcrestal approach and scalable augmentation volume. Four different biomaterials were inserted randomly (easy-graft CRYSTAL n = 38, easy-graft CLASSIC n = 41, NanoBone n = 42, BioOss n = 34), 2 ccm in each case...

Ziel: Gegenstand dieses systematischen Reviews, als Grundlage für ein Expertenkonsens, war die Beurteilung des Einflusses unterschiedlicher partikulärer Knochenersatzmaterialen (KEM) in lokalen Knochenaugmentationsprozeduren in Verbindung mit der Insertion dentaler Implantate auf Implantatüberleben und histomorphometrischen Ergebnissen. Material und Methoden: Folgende Indikationen wurden in Verbindung mit entweder simultaner oder verzögerter Implantation untersucht: externer oder interner Sinuslift sowie vertikale und/oder laterale Augmentation des Alveolarfortsatzes...

OBJECTIVE: The aim was to investigate histomorphometrically whether or not implant surface nanotopography improves the bone response under immediate loading simultaneous to sinus grafting. MATERIALS AND METHODS: Dual acid-etched titanium microimplants with/without crystalline surface deposition of calcium phosphate particles were placed in bilateral sinuslift areas grafted with a mixture of iliac crest bone and BioOss. Surface topography of microimplants was characterized using interferometry...

Platelet concentrates for surgical use are innovative tools of regenerative medicine, and were widely tested in oral and maxillofacial surgery. Unfortunately, the literature on the topic is contradictory and the published data are difficult to sort and interpret. In bone graft, implant and reconstructive surgery, the literature is particularly dense about the use of the various forms of Platelet-Rich Plasma (PRP) - Pure Platelet-Rich Plasma (P-PRP) or Leukocyte- and Platelet-Rich Plasma (L-PRP) - but still limited about Platelet-Rich Fibrin (PRF) subfamilies...

The results of sinuslift with bone alloplasty were analyzed in 42 patients through the period of 7 years after the treatment. Mucosal penetration occurred only in one case from 11 when the piezosurgical um't was used, but in 4 from 31, operated in the ordinary manner. Connective -- tissue transplant from the palatine area was successful in mucosal penetration closure.

BACKGROUND: The minimally invasive sinus floor elevation as first described by Summers is limited in the volume of augmentation that is possible. In contrast, the more invasive approach is the sinuslift of Tatum which is indicated for greater bone deficiencies. Therefore, a new technique was developed for transcrestal elevation of the sinus floor and alveolar ridge augmentation with bone dowels in press-fit technique. MATERIALS & METHODS: The crestal cortical bone is cut with a hollow grinder followed by an indirect sinus floor elevation with a plunger...

Augmentation procedures in the severely resorbed maxilla are standard techniques in preprosthetic surgery. Aim of the present study was to compare onlay bone grafting and sinus floor elevation with autogenous bone grafts in edentulous patients in terms of bone resorption of the posterior alveolar crest and implant survival in a 5-year longitudinal study. A total of 100 patients (53 female and 47 male patients) requiring augmentation using autogenous bone due to a severely resorbed maxillae were evaluated. The degree of resorption and bone quality were preoperatively estimated in panoramic radiographs according to Lekholm and Zarb...

In many cases alveolar ridge atrophy causes severe alveolar ridge deficiency in horizontal and vertical direction. In cases of severe atrophy of the edentulous maxilla a maxillary retrognathism results. In this article, a new technique of solving this problem prior to implant placement is described. In six patients with severe atrophy of the edentulous maxilla a sinuslift operation and placement of dental implants were carried out in the posterior maxilla. In the anterior part of the maxilla a segmental split osteotomy and placement of two miniplate distractors were performed...

Blood platelets are the main source of different bone healing and growth factors. Their role and use in sinuslifting will be discussed. Finally we discuss the technique and the results in our patient population.
