Abstract The immediate postextractional implant insertion is a specific way of surgical approach to implanto-prosthetic treatment. This article addresses the indications, advantages, and surgical techniques of immediate postextraction insertion, illustrated with a clinical case. Objectives: presentation of the indications, advantages and surgical procedure of immediate postextractional implant insertion. Materials and methods: The present study considered the presentation of a case in which we opted for the insertion of implants immediately postextractionally as a therapeutic attitude. Results and discussions: The advantages and disadvantages of this therapeutic technique were represented as follows. The advantage of this technique is given by the shortening of the time necessary to complete the treatment until the prosthetic phase, the disadvantage being represented by the insertion of the implant in positions sometimes less advantageous to the prosthesis. Also, the fact that we could not preserve the alveolar ridge, keeping the bone volume necessary to insert the implant in the best position of the prosthesis by complying with the biomechanical principles, made over time, a series of complications that occurred due to vicious insertion of the implant and non-compliance with those biomechanical principles. Conclusions: The analysis of the case as a whole, represents the main premise from which any dental treatment must be started, so that the functionality of the prosthetic and aesthetic reconstruction will have to be taken into account when we choose the best treatment option.

Maxillary Sinuses

The partially edentulous in the posterior maxilla bone is produced mainly by the loss of molars due to caries, periodontal disease and excessive force supported by the teeth of this sector. Dental implants greater than 10 mm, are rarely placed in this area due to a higher probability of failure for the low bone volume and bone quality poor. In the skull, in the post jawbone relationship, we find a pterygomaxillary buttress. This allows, in some situations, the rehabilitation of atrophic jaws by placing implants with a parasinusal angulation, avoiding surgical techniques or more complex procedure. The pterygoid implant is a possible treatment to rehabilitate the atrophic posterior maxilla, anchored in cortical bone of the pterygoid process. A case of placement of pterygoid implants in a woman 58 years old with a large pneumatization in both maxillary sinuses, with a remaining alveolar bone 1-2 mm is reported.

The loss of alveolar bone volume is a physiological consequence of tooth loss, which if not done carefully preserved and becomes a significant functional and aesthetic risk for the installation of osseointegrated dental implants. The dimensional differences of the alveolar ridge can be attenuated with different graft materials and surgical procedures. The presentation of this case illustrates one of the various surgical techniques to reduce bone resorption and maintain the volume of tissue to be rehabilitated in a more predictable manner and reducing problems in the future, thus increasing the chances of successful rehabilitation osseointegrated dental implant.

Over Time

The destruction of the tooth crown should be regarded as the cause leading over time to the disruption of the morphofunctional unity of the dentition and pathological condition of the entire dentoalveolar system. Untimely treatment of defects of hard tooth tissues leads to functional disorganization of the dentoalveolar system. The most eliminated defects are those of crowns of teeth determining the quality of aesthetics, phonetics, functions of biting and chewing. The destruction of the tooth crowns, which do not cause significant disruption of the above functions, are painless and almost asymptomatic. In such cases, deformation of the dentition and occlusion, dysfunction of masticatory muscles and temporomandibular joints as well as the development of pathological changes in periodontium occur slowly. Of great importance are the early diagnosis of pathological reconstruction of dentoalveolar system and the knowledge of pathogenesis of possible complications after the extraction of the teeth that determine the indications for prophylactic orthopedic dental treatment. The article presents a clinical case of restoration of destructed tooth crown 3.6 complicated by changes in bifurcation area. The patient underwent coronary-radicular separation with the use of cast metal cores, which allowed restoration of the sufficient size of the stump, function and anatomical shape of the tooth and hence the unity of dental arch.

The aim of this study was to measure the convexity of the lateral wall of the maxillary (Mx) sinus and identify the locational distribution of antral septa in relation to the zygomaticomaxillary buttress (ZMB), in order to suggest another anatomical consideration and surgical modification of sinus floor elevation procedures. This study was designed as a cross-sectional study, and a total of 134 patients and 161 sinuses containing edentulous alveolar ridges were analyzed. The angle between the anterior and lateral walls of the Mx sinus (lateral sinus angle [LSA]), and the angle between the midpalatal line and the anterior sinus wall (anterior sinus angle [ASA]) were measured. Mean LSAs and ASAs were 105.9° ± 9.86° and 58.4° ± 6.43°, respectively. No significant difference between left and right sides was found (LSA, P = .420; right = 105.5° ± 9.27°; left = 105.5° ± 9.27° and ASA, P = .564; right = 57.9° ± 6.80°; left = 58.8° ± 6.02°). The prevalence of septa was 37.3%, and it was most frequently noted in the second molar region (32.8%), followed by the first molar (20.9%), retromolar (16.4%), and second premolar regions (14.9%). Septa were most frequently located posterior to the ZMB (49.2%), while ZMB was mostly located in the first molar region (66.4%). Narrow LSAs may complicate the surgical approach to the posterior maxilla, especially when sinus elevation should be used in the second molar region. Considering the occasional presence of antral septa, membrane elevation may be complicated when a septum is encountered during the procedure. These results suggest that 3-dimensional examination of the convexity of the Mx sinus should be performed preoperatively to choose proper surgical techniques and minimize surgical complications.

Abstract Objectives The aim of this study was to assess whether alveolar ridge preservation (ARP) can reduce the need of ridge augmentation at posterior tooth sites. Material and methods This study enrolled patients who received dental implants at posterior tooth sites during 2013–2019. Demographic data and dental treatment histories were collected. Based on healing patterns after tooth extraction, patients were divided into ARP and spontaneous healing (SH) groups. Three surgical treatment plans were devised according to the alveolar bone volume on cone-beam computed tomography (CBCT). The three treatment plans were to perform implant alone, simultaneous guided bone regeneration (GBR) and implantation, and staged GBR before implantation. Statistical analyses were performed to determine relationships. Results There were 92 implant records in the ARP group and 249 implant records in the SH group. A significant intergroup difference was observed regarding the frequency distribution of the treatment modality of staged GBR before implant (χ2 = 15.07, p = 0.0005). Based on the implant alone treatment modality and simple logistic regression, the SH pattern was related to staged GBR before implant (SH vs. ARP: crude odds ratio (OR) = 4.65, 95% confidence interval (CI) = 2.15–11.61, p = 0.0003). After adjusting confounding factors, the risk was still significant (adjusted OR = 5.02, 95% CI = 2.26–12.85, p = 0.0002). Conclusions The study results suggested that ARP is more likely to lead to the treatment modality of implant alone and reduce the need for staged GBR before implantation. Clinical relevance This study describes ARP capable of minimizing the need for staged GBR before implantation and shortening the treatment duration.

Background: The volumetric and biological behaviors of equine block grafts compared with autogenous block grafts have not yet been assessed. Hence, the aim of the present study was to compare—by means of histomorphometry, immunohistochemistry and microtomography—the graft incorporation and remodeling processes of autogenous and equine xenogenous bone blocks used for mandibular lateral augmentation in rabbits. Methods: Autogenous bone grafts harvested from the iliac bony crest and equine block grafts were secured to the lateral aspect of the mandible angle of eighteen rabbits. The healing after 7, 20 and 60 days was assessed in six animals each period. Results: After 60 days, new bone was present 24.2 ± 11.2% and 31.6 ± 13.3% in the autograft and xenograft groups, respectively. A better integration to the recipient sites was observed in the autogenous compared with the xenogenous blocks. Conclusions: Both xenogenous and autogenous bone blocks presented similar percentages of newly formed bone over time. However, bone volume, the quality of the grafted area and graft incorporation to the recipient sites were superior in the autogenous compared with the equine xenogenous graft sites.

Objective: This case report aims to present the microdontia treatment of tooth 35 through pre-prosthetic orthodontics, followed by re-anatomization with an indirect restoration. Case report: A 21-year-old female patient presented with microdontia in tooth 35, with a distalized and vestibularized crown. In addition, tooth 34 was gyroverted with mesial diastema. Orthodontic mechanics with segmented arch were used to centralize tooth 35 in the alveolar ridge, close the diastema in the mesial of tooth 34, and correct its gyroversion. For lingualization of tooth 35, a first-order fold (in set) was performed, and for mesialization, an open-coil spring was used between teeth 35 and 36. A closed-coil spring was used to delimit the movement of tooth 35 to mesial. The force applied by the open spring for mesialization of tooth 35 was transmitted to tooth 34, through the closed spring, resulting in its mesialization; this, closed the diastema between teeth 33 and 34 and corrected the gyroversion. Subsequently, the coronary preparation was performed with diamond tips 1014 and 3146, and confection of the temporary crown in acrylic resin. For the ceramic system, IPS™ e.max Press was used. The ceramic crown was luting using the adhesive technique, followed by light curing for 40 seconds on each face of the tooth. Conclusion: It can be concluded that the re-anatomization of a small tooth should be the first treatment option. However, pre-prosthetic orthodontic treatment may be necessary.

Subject. With the advent of advanced imaging technology and CAD/CAM technologies, the possibility of guided surgery has become of wide interest among implantology. The article is devoted to the use of surgical template implantation in the rehabilitation of a dental patient. It provides information about some advantages and disadvantages of the digital protocol in comparison with traditional dental implantation. The main stages of navigation surgery in a clinical case are described. Goal. To evaluate the actual clinical advantages and disadvantages of dental implant placement using a surgical template compared to the traditional treatment protocol. Methodology. The literature search was conducted in scientific search bibliographic databases such as PubMed, eLIBRARY, Medline, and Google Academy. More than 384 studies up to 2014 were found under the thematic headings "Dental implantation" and "Surgical template". During the study of these works, the sample included 56 articles and literature reviews. Conclusions. Recently, implant placement using a surgical template has become a popular treatment method among dental surgeons. The study of modern literature allowed us to formulate the main advantages and disadvantages of this method. Advantages of the method: precise positioning of implants; flap-free surgery reduces the operation time and is characterized by a favorable postoperative course; integration of restoration determinants in surgical planning, which leads to a more aesthetic, functional and predictable result of prosthetics; the possibility of pre-manufacturing a prosthesis based on the planned position of the implant; simplification of the surgical procedure for the dentist. However, this method is not without its drawbacks: the surgeon's inability to visualize anatomical structures; the risk of axis and depth deviation during implant placement; requires additional digital planning.
