Abstract Selected factors and opinions are reviewed specific to immediate function of dental implants in terms of biomaterial and biomechanical properties and how they might influence postsurgical tissue healing. Comparisons are made among plate, rod, and screw vs plateau, finn, and porous geometry endosteal dental-implant designs with and without alterations in device body-surface microchemistry and microtopography. Available information introduces more questions than answers, and recommendations are made for ongoing studies of bone responses specific to the implant fit and fill parameters focused on the kinetics of postsurgical osteotomy healing and applied loading. The clinical literature supports opportunities for immediate function; however, proposals about pathways for bone healing need further investigation. The current trends within the discipline of implant dentistry offer opportunities to reevaluate current vs previous immediate-function systems.

Introduction: Implant dentistry is one of the fastest growing specialty in the field in dentistry. Yet there is a paucity of literature regarding the prevalence and the current trends of implant dentistry practice among dentists working in Nepal. Thus, the objective of this study was to assess the prevalence and current trends of dental implants practice among the dentists working in Nepal. Method: A cross sectional, online study was done among 267 Nepalese dentists from October, 2020 to December, 2020 by convenience sampling method. Data collection was done with the help of a proforma that included socio-demographic details and predesigned questionnaire adopted from a study done in Mumbai, India.13 The questions were developed in google form and shared to the study participants through various social media for the study duration of 3 months. Results: Out of 267 participants, 142 (53.2%) were BDS, 107 (40.1%) were MDS and remaining had other degrees. Of the total participants, only 83 (31.1%) placed dental implants in their practice. Those who did not place dental implants referred the case mostly to periodontist (51.1%), followed by prosthodontist (34.8%). Only 72 (26.9%) had undergone formal implant training program. All the study participants prescribed radiograph as CBCT alone or in combination with the other radiographs. Most of the participants, who placed dental implant, did both the surgical and the prosthodontic phases. Bone level implants (74.7%), Screw retained (50.6%) and extra oral fixation (50.6%) type prosthetics were used by most of the participants. Most frequently used implant systems were Bredent (46.9%), Nobel Biocare (46.9%) and Straumann (46.9%) followed by Adin (44.5%). Conclusion: The current study showed that dental implants practice is adopted by less than one third of the dentists in Nepal, that suggests the need for implementation of Continuing Professional Development in dental implants in Nepal to increase the knowledge and skills among dental professionals.

Due to growing demand for metal-free dental restorations, dental ceramics, especially dental zirconia, represent an increasing share of the dental implants market. They may offer mechanical performances of the same range as titanium ones. However, their use is still restricted by a lack of confidence in their durability and, in particular, in their ability to resist hydrothermal ageing. In the present study, the ageing kinetics of commercial zirconia dental implants are characterized by X-ray diffraction after accelerated ageing in an autoclave at different temperatures, enabling their extrapolation to body temperature. Measurements of the fracture loads show no effect of hydrothermal ageing even after ageing treatments simulated a 90-year implantation.

Introduction: Ozone is a potent antioxidant that acts as a precursor of various radicals, being indicated as a powerful therapy, assisting in the process of tissue healing. Objectives: The proposal of this study was to analyze material and structural properties via mechanical testing in tibias after application of ozone in bone defects produced surgically. Methods: Ten male 40-day old albino Wistar rats have been used, divided in two groups: control group and ozone group, this last one being treated with ozonized water in 25 µg/mL of concentration until the day of euthanasia. Trichotomy and longitudinal incision was conducted in the animals’ leg skin, exposing the tibia’s diaphysis of both antimers, and with help of a high rotation pen a flaw has been produced on the bone. After 60 days of surgery the animals were euthanized, and tibias were collected for biomechanical analysis. Results: The results of the biomechanical properties – structural and material – evidenced significant interactions through exposure to ozone, showing a diminished bone resistance in animals from the control group, observed by the decrease of the maximum force (N) needed to rupture the bone when compared to the value needed to break the bones of the animals from the ozone group, and the analysis of the morphometrical properties did not show any difference between both experimental groups. Conclusion: The use of ozone did not alter the morphological structures of the tibias, and the group which used ozone presented more resistance during mechanical testings, because the maximum force for the rupture of tibia was greater in this group.

Introduction of dental implants and more concern in patients about esthetics after loss of natural teeth increases the demand of bone grafts. Various types of bone grafts as allografts, xenografts and autografts are used all with their own pros and cons. Bone grafts are more likely to succeed when the conditions at the recipient site are favourable and certain requirements are fulfilled. This review explores the use of various bone grafts in implant dentistry.

Introduction: Digital radiography can take accurate measurements. In implant dentistry, intraoral periapical (PA), bite-wing (BW) and panoramic (OPG) radiographs are being used, although it had limitations of distortion. This research aims to assess the accuracy of digital radiography in measuring dental implants and to evaluate the SIDEXIS software’s reliability in measuring their dimensions.Materials and Methods: Over 192 implants from 316 radiographs were selected. All radiographs were analyzed using SIDEXIS software. Statistical analysis was performed using SPSS.Results: Statistically significant differences (P < 0.5) between the actual heights and widths compared to the measured radiographic dimensions. Over all the distortion was greatest in OPGs. The magnifications were 2.48mm in height and 0.82mm in width for OPGS, 0.17mm in width for BWs while in PAs it was 1.37mm in height and 0.156mm in width. The magnification was more in maxilla for PAs and OPGs. Anteriorly the PAs had the greatest magnification (2.16mm), and OPGs had the greatest at (3.03mm) in height posteriorly.Conclusion: Digital OPG, PA and Bitewing radiographs are reliable for performing dimensions linear measurements for implants, and PAs have the highest precision. Additionally, SIDEXIS software provided accurate results and can be considered a reliable method for implants’ assessment.

Tendon inserts into bone via a fibrocartilaginous interface (enthesis) that reduces mechanical strain and tissue failure. Despite this toughening mechanism, tears occur because of acute (overload) or degradative (aging) processes. Surgically fixating torn tendon into bone results in the formation of a scar tissue interface with inferior biomechanical properties. Progress toward enthesis regeneration requires biomaterial approaches to protect cells from high levels of interfacial strain. We report an innovative tissue reinforcement strategy: a stratified scaffold containing osseous and tendinous tissue compartments attached through a continuous polyethylene glycol (PEG) hydrogel interface. Tuning the gelation kinetics of the hydrogel modulates integration with the flanking compartments and yields biomechanical performance advantages. Notably, the hydrogel interface reduces formation of strain concentrations between tissue compartments in conventional stratified biomaterials that can have deleterious biological effects. This design of mechanically robust stratified composite biomaterials may be appropriate for a broad range of tendon and ligament-to-bone insertions.

ABSTRACTAfter tooth loss, an individual may seek tooth replacement so that his/her function and esthetics could be restored. Clinical prosthodontics, during the past decade, has significantly improved and developed according to the advancements in the science and patient's demands and needs. Conventional options in prosthodontics for substituting a missing single tooth include the removable partial denture, partial and full coverage bridgework, and resin-bonded bridgework. Dental implants have gained increasing popularity over the years as they are capable of restoring the function to near normal in both partial and completely edentulous arches. With substantial evidence available, fixed implant-supported prosthesis are fully acknowledged as a reliable treatment option for the replacement of single or multiple missing teeth nowadays. While dental implants are increasingly becoming the choice of replacement for missing teeth, the impediments associated with them are progressively emerging too.
