“…Clinical studies have shown that the IML protocol is a suitable alternative to conventional two-stage implants based on the prevalence of post-operative negative clinical outcomes such as osseointegration failure, implant mobility, pain and discomfort. 1,2 Similar findings were found in animal experiments [3][4][5][6] and human histological studies. 7,8 A systematic review of clinical studies concluded that it is possible to successfully load dental implants immediately or soon after their placement in selected patients, although failure rates tend to be greater when compared with conventional loaded implants.…”

Objective: The aim of this study was to assess longitudinal quantitative changes in bone density around different implant loading protocols and implant surfaces measured by digital subtraction radiography (DSR). Methods: 12 patients received bilateral homologous standard and TiUniteH (Nobel Biocare, Kloten, Switzerland) single-tooth implants under 2 implant-loading protocols: immediate loading (8 patients, 16 implants, 12 maxillary) and conventional loading (4 patients, 8 implants, 4 maxillary). Standardized periapical radiographs were taken immediately after implant placement (baseline image) and at the 3-month, 6-month and 12-month follow ups. Radiographic images were digitized and submitted to digital subtraction using the DSR systemH (Electro Medical System, Nyon, Switzerland), resulting in three subtracted images. Quantitative analysis of bone density was performed using Image ToolH software (University of Texas Health Science Centre, San Antonio, TX) to assess pixel value changes in five areas around the implants (crestal, subcrestal, medial third, apical-lateral and apical). Results: Repeated-measures analysis of variance showed that grey levels were significantly influenced by follow-up time and implant-loading protocol. A linear increase in grey levels was found for immediate loading (IML) implants and a significant decrease in grey levels was observed in the 12-month follow up for conventional loading implants. No effect of implant surface treatment was observed. Conclusion: In conclusion, IML protocol induced mineral bone gain around single-tooth implants after the first year under function for cases with favourable bone conditions.

“…From the mid-1990s to date, it has been experimentally demonstrated that osseointegration is improved and accelerated through various roughening procedures [67,68], such as sand blasting [69][70][71], acid etching [72][73][74], anodic oxidation [75][76][77], and even laser etching [67,68,[78][79][80], and that there exists an optimal range in the micrometer scale [81]. The so-called moderately microroughened implant surfaces have been proven to present improved osseointegration in experimental and in clinical studies [82,83].…”

“…The percentages of bone-to-implant contact and the bone density of the anodized implants were observed to be 57.03±21.86 % and 40.86±22.73 %, whereas the machined implants were 37.39±23.33 % and 3.52±4.87 %, respectively. Burgos et al 34 Despite titanium's biological compatibility, it is considered to be an inorganic material. This means that the metal does not form part of the human body.…”

Dental implants are mechanical components that are used to restore the mastication (chewing) function and/or aesthetic appeal because of tooth loss or degradation. They are affixed (screwed) into the upper or lower jaw and act as a base for single or bridge-type tooth replacements. They are mostly manufactured from titanium alloys. The surface integrity of the manufactured implant may have a significant effect on the functioning and success of the implant. A systematic review is described on the effect of engineered surface integrity on the performance of titanium dental implants as regards the implant fixation, mechanical performance, bone growth and cell response. The need for surface engineering of the implant is introduced first. This includes the mechanical, surface-integrity and biocompatibility-required properties. This is followed by introducing and discussing the dedicated surface-modification processes currently employed. These include: abrasive blasting, electrochemical processes, hybrid processes and laser modification. The mechanical and biocompatible properties of an implant are the most crucial factor for their application in biomedical use. Hence, the present review article focused on the latest improvements to dental implant design based on the mechanical and biocompatible properties. The physical contact of an implant with respect to its surface roughness is an important factor in dental implant design. The surface roughness of an implant on the macro, micro and nano scales have specific effects on the implant's contact with the surrounding tissue of the bone. In addition, the biocompitability of titanium material is very important to develop a sustainable dental implant. Looking into the importance of the above mechanical and biocompatible properties of bone implants, the authors review elaborately the development of titanium-based implants with reference to the above properties. Keywords: implants, titanium, surface roughness, systematic review, surface engineering process, hybrid process, mechanical machining, chemical treatment Zobni vsadki so mehanske komponente, ki se jih uporablja za obnovo funkcije`ve~enja in/ali iz estetskih razlogov zaradi izgube ali poslab{anja zoba. Pritrjeni (privija~eni) so v zgornjo ali v spodnjo~eljust in slu`ijo kot osnova za nadomestni zob ali za mosti~ek. Ve~inoma so izdelani iz titanovih zlitin. Integriteta povr{ine izdelanih vsadkov lahko pomembno vpliva na delovanje in uspe{nost vsadka. Opisan je sistemati~en pregled o vplivu in`enirske celovitosti povr{ine na zmogljivost titanovega dentalnega vsadka glede na pritrditev vsadka, mehanske zmogljivosti, vra{~anja kosti in odziva celic. Najprej je predstavljena potreba po obdelavi povr{ine vsadka. To vklju~uje zahtevane mehanske lastnosti, celovitost povr{ine in biokompatibilnost. Temu sledi predstavitev in razlaga trenutno uporabljanih postopkov za namensko spremembo povr{ine. To vklju~uje: abrazivno peskanje, elektrokemijske procese, hibridne procese in modifikacijo z laserjem. Mehanske in biokompatibilne la...
