“…It showed very good mechanical properties and excellent osseointegration. Moreover, in many clinical prospective studies, narrow-diameter implants in categories 3 and 2 had very good performance when they supported fixed partial dentures [23][24][25]. Recently, in 2019, the new mini-implant system (category 1 of narrow implants, 2.4 mm wide) made of the Roxolid ® (Ti-Zr) alloy (Straumann ® Mini Implant System) was released on the dental market.…”

The new Ti–Zr (Roxolid®) mini-implants have not yet been fully researched. We analyzed peri-implant and posterior edentulous area microstrains during mandibular overdenture (OD) loading at different sites with different extents of forces when one-, two-, three-, or four- mini dental implants (MDIs) as single-units supported the respective ODs. The models were designed from cone beam computed tomography (CBCT) scans of an appropriate patient with narrow ridges. The mucosal thickness was 2 mm. Strain gauges were bonded on the vestibular and oral peri-implant sites, and in the distal edentulous area under the saddles. The loads were applied posteriorly bilaterally and unilaterally with 50, 100 and 150 N forces, and anteriorly with 50 and 100 N forces. Each loading was repeated 15 times. Statistical analysis included descriptive statistics, boxplots and the MANOVA. Higher forces induced higher peri-implant microstrains, as well as unilateral loadings, especially on the loaded side, in all models except the one-MDI model where anterior loads (100 N) elicited the highest peri-implant microstrain (1719.35 ± 76.0). The highest microstrains during unilateral posterior loading (right side) with 150 N force were registered from the right MDI in the two-MDI model (1836.64 ± 63.0). High microstrains were also recorded on the left side (1444.48 ± 54.6). By increasing the number of implants, peri-implant microstrains and those in the edentulous area decreased. In the three- and four-MDI models, higher microstrains were found in the posterior than in the anterior MDIs under posterior loadings. None of the recorded microstrains exceeded bone reparatory mechanisms, although precaution and additional research should be provided when only one or two MDIs support ODs.

“…Застосування методу дентальної імплантації суттєво розширило межі показань до незнімного варіанту протезування в умовах амбулаторного прийому, перевагами якого є простота та передбачуваність клінічного протоколу та максимально позитивне сприйняття з боку пацієнтів [1]. Імплантація стала методом вибору для заміни відсутніх зубів у частково беззубих ділянках [2,3].…”

Literary data testify to the significant prevalence of the dental implantation method to solve the problem of permanent prosthetics in partial and complete anodontia. However, a significant array of information needs systematization and generalization, taking into account the specifics of providing dental care by dental institutions in different regions. The authors conducted a retrospective study of the main statistical regularities based on the results of 32 cases of treatment of secondary anodontia by replacing bounded and finite distally unlimited defects of the lower and upper jaws with the support of dental endosseous implants as exemplified by outpatient care at a private dental office in the city of Poltava (Ukraine). Dental implantation and subsequent prosthetics were performed at one medical institution, by one doctor in cooperation with one dental laboratory in the city of Poltava (Ukraine). The term of retrospective observation was 5 years. The condition for inclusion in the study was the manufacture of a non-removable orthopedic appliance with the non-removable fixation on dismountable and full-body intraosseous screw dental implants. In all cases, metal and ceramic structures with cement fixation on intraosseous dental implants of the Implife Classic, Implife Solo (Inpride company, Ukraine) Vitaplant VK Vitaplant V2Kn (Vitadent company, Ukraine) implant systems were manufactured. Observation of the treatment outcomes was carried out an average of 32 months after the fixation of 69 orthopedic appliances. It turned out that the protocol of permanent prosthetics to replace partial defects of the dentition was implemented mainly in the middle-aged group. Periodic outpatient monitoring of orthopedic appliances with cement fixation on intraosseous implants takes place within the period from 6 to 60 months. The average observation period was 32.8 months. Characteristic statistical regularities related to the selection of individuals and the most common types of implants for solving standard clinical tasks were determined. The average number of implants per clinical case was 4 supports, and the average diameter and length of the integrated implants were 3.5 and 11 mm, respectively.

“…In these cases, other procedures have been proposed to overcome the limitations in the posterior maxilla or mandible. Short implants as the least intrusive treatment are indicated [ 7 , 8 ]. When the bone height is insufficient even for short implants, other procedures may be used, including bone grafting and zygomatic implants.…”

Background Many clinical studies have reported the high success rate of the All-on-4 concept. In the present study, we aimed to compare the stress distribution with different tilted distal implants and cantilever lengths in an All-on-4 system using the two-dimensional photoelastic method and to establish the All-on-4 implant photoelastic model by computer-aided design (CAD) and rapid prototyping (RP). Methods The data of the human edentulous mandible were acquired by computed tomography (CT). Three human edentulous mandible All-on-4 implant models with different distally inclined implant holes were fabricated using Mimic, Geomagic Studio software, and a light solidifying fast shaping machine. Then the final photoelastic models were established through the traditional method. Each of the three models had four NobelSpeedy Replace implants between the interforaminal regions. The two posterior implants were placed 0, 15, and 45 degrees distally before the mental foramen. The four implants were splinted by wrought cobalt-chromium alloy frameworks. Each of the three photoelastic models was submitted to a 150 N vertical load at five points on the framework: the central fossa of the mandibular first molar, and 0 mm, 5 mm, 10 mm, and 15 mm of the cantilever length. The stress produced in the models was photographed with a digital camera, and the highest value of the stressed fringe pattern was recorded. Results The All-on-4 implant photoelastic model established by CAD and RP was highly controllable and easy to modify. The position and inclination of implants were accurate, and the frameworks could be passively emplaced. The stress values were higher around a single tilted implant compared with the distal implant in All-on-4 with the same inclination. The 0-degree distal implant and 45-degree distal implant demonstrated the highest and lowest stress when loading at the central fossa of the mandibular first molar, respectively. With the same inclination of distal implant, the peri-implant bone stress increased as the length of cantilever increased. Conclusion The method of establishing the All-on-4 implant photoelastic model by CAD and RP was highly controllable, convenient, fast, and accurate. The tilted implants splinted in the fully fixed prosthesis with reduced cantilever lengths did not increase the stress level compared with the vertical distal implants.And this illustrated that the influence of cantilever on stress distribution was greater than the influence of implant inlination.
