“…A sensor associated with the stereolithographic guide could reduce and even eliminate the risks and deviations reported in the literature. 17 It is necessary to emphasize that this was the first experiment related to a digital reflectance sensor for implant installation. Several difficulties appeared during the use of the sensor, among them the delay in display the accurate distance of the drill bit, so the expected alarm to avoid perforations may be late.…”

Objectives The aim of this research was to develop a sensor of approximation by reflectance for guided surgery with dental implants without flap detachment, and verify the effectiveness of this system. Materials and Methods Ten models of total edentulous arches were divided into two groups. Two implants of 3.5 × 11.5 mm (NeoDent) were inserted in each model; in Group 1 (G1), a stereolithographic guide NeoGuide system was used. In Group 2 (G2), the experimental approximation sensor was used for the insertion of the implants. The evaluation of the results was performed by overlapping the virtual planning images with the tomographies of the models of the implants inserted. Results There were no statistically significant differences between the guide and the sensor groups. The averages and standard deviations observed at the angulation of the guide was 4.15 (2.65 degrees) and 5.48 (2.85 degrees) at the sensor. The linear deviations at the cervical level were 0.002 (1.37) and 0.11 (1.47) mm and at the apical level 0.19 (1.28) and 0.21 (1.42) mm, respectively. Conclusions The use of a guide is important for the stabilization of the drills; the greatest challenge is to control the apical position of the implants, especially in highly reabsorbed edges. The experimental sensor can become an auxiliary tool to the stereolithographic guides; however, several difficulties must still be overcome to recommend the use of a sensor.

“…On the opposite, the choice of guided surgery allows you to completely plan the intervention. Even with the intrinsic limits of this method, for example the precision of CBCT exams or the precision of the surgical masks, there is no doubt that the operations can be performed with a clearly superior reproducibility of some parameters [ 30 , 36 ]. Choosing a digital prosthetic flow allows more advantages.…”

Replacing a single tooth in the anterior maxilla is one of the greatest challenges in dentistry. Both functional and aesthetic results are to be strictly pursued. Planning and executing such a case through a totally digital methodology eventually guarantee many advantages, above all patient’s operative and postoperative comfort. To ascertain this, a BOP analysis was performed which allowed us to evaluate soft tissues health, and more; crestal bone resorption was measured to evaluate hard tissues stability. This assumption was studied through four cases in which patients were alternatively treated with analogic and digital techniques. Four homogeneous patients were recruited. They all needed to extract one of the upper incisors, due to different clinical reasons, and then to replace it with an implant. Each patient was treated with an immediate postextractive implant which was immediately loaded, and finally, analogical and digital techniques were compared. All patients underwent a preoperative CBCT examination. After surgery, patients were checked by the surgeon after 10 days and one month to evaluate the progress of healing and to exclude any prosthetic problem. At 6 months (T1), one year (T2), and three years (T3), intraoral x-rays were performed using customized centring devices, according to the parallel beam technique. All data have been collected in a table and statistically processed; mean and standard deviation were measured. All patients entered an oral hygiene program with six months recall. Dental hygienist checked the BOP at T1, T2, and T3. At every step, similar levels of BOP were recorded. About interproximal bone loss, all patients showed an initial moderate loss (between T1 and T2), followed by stable values between T2 and T3. Despite the important limitations of a study with few cases, these results show a similar outcome comparing digital and analogical methods.

| INTRODUC TI ONDental implant therapy is a well-established dental treatment modality that provides benefits for edentulous and partially edentulous patients. Edentulism is a toothless condition that affects well-being and life quality. Although the prevalence of complete tooth loss has declined since 2002, edentulism remains a major disease worldwide, especially among older adults. 1 According to several studies, tooth loss can affect general health in a number of ways owing to reduced intake of a vitamin-rich diet. 2 Also, it has been demonstrated that the dentition status can impact the healthy eating index score and overall diet quality. 3 Edentulism is significantly associated with depression and poor self-rated health in patients younger than 50 years. 4 Furthermore, in a recent systematic review that evaluated mortality and the rehabilitation of edentulism, a possible relationship was found between death rate and edentulousness, in that death rate was higher among edentulous patients not using dentures compared with denture wearers. 5 Therefore, oral health-care providers should prevent tooth loss with proper dental education and improved treatment quality to rehabilitate the edentulous and partially edentulous patients and reestablish proper masticatory function.Dental implants are a valuable treatment option for improving oral health and quality of life, especially for completely edentulous patients. 6 However, dental implants can fail at different points in time, starting from the moment when they are inserted. Based on the time when the failure occurred and the time of loading, early and late failures have been described. 7 However, implant therapy also can present complications, which do not necessarily lead to implant failure.Therefore, the aim of this volume of Periodontology 2000 is to present an overview on the causes of various types of complications related to implant therapy and to provide the practitioner with clinical concepts on their prevention and management. | BONE DYNAMI C AC TIVIT Y FROM TIME OF IMPL ANT PL ACEMENTThe dental implant treatment process starts with comprehensive planning, followed by surgical management of the alveolar bone to prepare it to receive primary (mechanically) stable implant(s) and implant restoration(s) that are resistant to occlusal loads and meet the functional and esthetic demands of patients. However, complications (biological, surgical, or prosthetic) may be encountered. During surgery, strong dynamic and active processes are present in peri-implant tissues, which are induced by trauma during flap and periosteum elevation at the time of implant insertion and the response of the surrounding tissues to the implant material (ie, titanium). The peri-implant bone density is altered (modified) as a result of bone removal (osteotomy) and subsequent bone condensation (ie, through the use of osteotomes or osseodensification, or undersizing of the osteotomy), and bone density continues to improve by stimulating the surrounding bone using functional loading. This st...
