Book Description
Background: Short implants have been described as a treatment option to avoid complementary surgical procedures in cases of limited bone height. In order to increase the biomechanical properties of short implants, implant manufacturers have developed different implant surfaces and macroscopic topographies. More recently, bone level short dental implants with SLA surfaces have been launched into the market, but still there is a lack of information regarding medium-long-term survival rates.Aim: Retrospective study to evaluate the medium-term survival rates of 8-mm length bone level SLA-surfaced implants with at least 1-year follow-up.Methods and Materials: This single center retrospective study was based on the clinical records of patients who underwent dental implant therapy with Straumann Bone Level Tapered 8mm (BLT8) implants between January 2017 and April 2018 and complied with the mandatory follow-up visits. All patients were treated by a skilled surgeon with BLT8 implants using a standardized protocol. Data regarding maxillary location, regeneration procedure, date of surgery, date and time of loading, final follow- up appointment as well as patient rehabilitation (single unit, partial, total) were obtained following ethics committee approval.Early failure was defined as an implant that failed to integrate and was removed before 6 or 3 months for implants placed with and without regenerative procedures, respectively. Late failure was defined as implant removal with prosthetic loading following the osteointegration period.Results: A total of 214 BLT8 implants were inserted in 99 patients. 115 (53.7%) implants had a regular diameter of 4.1mm and 99 (46.3%) a narrow diameter of 3.3mm. The posterior mandible (36.0%) and the posterior maxilla (29.9%) were the most frequent locations, as opposed to the anterior mandible, which presented the lowest percentage of short implants placed (13.1%).Immediate loading was performed in 75 (35.0%) implants and mostly used as posterior implants in full arch rehabilitations. 212 implants received prosthetic load, of which 86.0% were over splinted implants and 14.0% over single unit implants.214 implants were evaluated for early failure and 212 for late failure. Of those, one implant failed in each evaluated period, which resulted in a survival rate of 99.5% for early and late failure with no statistical differences between them (p>0.05). Conclusions and Clinical Implications: Within the limitations of this study the Bone Level SLA-surfaced 8 mm length implants showed high survival rates within the evaluated follow up period, comparable to those described in the literature for the standard-length implants. Further follow-up studies with larger samples and longer follow-ups are required to identify factors that could interfere in the survival and success rates of short dental implants.

Book Description
Background: Implant placement is often difficult to achieve in the atrophic maxillae due to limited ridge height. The use of short implants has been suggested as an alternative treatment option to vertical bone augmentation. However, there is still a lack of information concerning the long-term predictability of short implants.Aim: The aim of this retrospective study is to evaluate the survival rate of short SLA-surfaced implants with 6- and 8 mm lengths and at least 1-year follow up.Materials and Methods: All patients that had dental implant therapy with short implants between 01 January 2015 and 31 December 2018 that complied with mandatory follow ups were included in this retrospective study. Following ethic committee approval, data was retrieved from treatment records concerning patient characteristics, total or partial edentulism, implant characteristics, anatomical location of the implant, type of regeneration procedure, time of loading, date of placement, failure and final follow-up appointment. All patients in the study were treated by 3 experienced surgeons with Straumann Tissue Level comprising 6- (TL6) or 8 mm (TL8) implants, using a standardized surgical procedure. Early failure was defined as an implant that failed to integrate and was removed before 6 or 3 months for implants placed with and without regenerative procedures, respectively. Late failure was defined as implant removal with prosthetic loading following the osteointegration period.Results: A total of 199 patients received 191 TL6 and 156 TL8 dental implants with a follow up that ranged between 1 and 4 years. Most of the implants (93.7%) had a diameter of 4.1 mm, with the others (6.3%) having a diameter of 3.3 mm. The most frequent indication for short implant placement was the restoration of a partially edentulous arch (59.8%). The most common locations were the posterior mandible (63.4%) and the posterior maxilla (32.6%). The success rates for early failure were 98.4% and 99.4%, and for late failure (n=326) 99.4% and 99.3% for TL6 and TL8, respectively. No significant statistically differences were found regarding the different lengths for early and late failure (P>0.05).Conclusions and Clinical Implications: Within the limitations of this retrospective study, the 6- and 8 mm SLA implants evaluated demonstrated an overall medium-term survival rate with no significant differences between them, which may be compared to that of standard-length implants.

Book Description
Purpose: The main objective of this retrospective study was to compare the clinical outcomes of 6mm implants (Test group) vs. 8mm implants (Control Group) in terms of success, survival, marginal bone loss and periodontal parameters.Material & Methods: Implants placed in the Clinica Universitaria Odontologica at Universitat Internacional de Catalunya between 2005 and 2015 were evaluated. Control visits were performed evaluating the following parameters (present complications, periodontal parameters, probing depth, bleeding on probing, plaque index, suppuration), periapical radiographs were performed to determine bone loss from prosthesis delivery to check-up visits, and clinical records were reviewed for possible complications. Results: A total of 114 implants were reviewed, 68 implants of 6mm and 46 implants of 8 mm. Total survival rate of the test group was is 94,1%, having 4 failures. A single failure was found in the control group, corresponding to a survival of 97,8%. Regarding success rates, according to Buser criteria, in the control group 87,5% of the the implants meet the requirements to be considered successful vs only 64,2% of implants in the test group. The mean marginal bone loss in the control group was 0,43 u00b1 0,24 mm in mesial and 0, 59 u00b1 0,44 mm in distal, while 0,81 u00b1 0,33 mm in mesial and 0.59 u00b1 0,36 mm in distal were found in the test group. All factors were analyzed with a mean follow-up period of 4.5 and 5 years respectively between test and control group. Conclusions: Within the limitations of the study, 6mm implants show more unfavorable results regarding survival, success and levels of marginal bone loss compared to 8mm implants in an average follow-up time of of 4.5 and 5 years respectively between test and control group. 8mm implants could be considered a more valid therapeutic option.

Book Description
Title : Retrospective study of marginal bone loss around two implants systems conducted by radiographic evaluation Type of Presentation Poster display V Author : Hee-Won Jang, Jeong-Kyung Kang, Young-Il Jang Abstract: Purpose : The aim of this study was to analyze the amount of marginal bone loss(MBL) around implants to establish the difference between RBM and SLA surface. Background : This study present the amount and differences of MBL in two implants which have different surface treatment. Materials and Methods : one hundred and twenty implants were placed in the posterior maxilla and mandible in sixty patients. Data were collected in terms of age, implant length, width and etcClinical and radiographic examinations were performed during all procedure by one dentist. MBL was evaluated on the base of three intervals i.e. at the time of loading(baseline), and annually up to one year and 3 years. One dentist placed implants and fabricated restorations during the procedure. The type of them were gold. All of restorations were crowns. They were not removable restorations. Measurements to the nearest 0.1mm were taken at the mesial and distal site, and the average values were calculated for each implant. Two way-ANOVA test was used to verify the significance of the mean MBL in RBM and SLA surface, which present internal connection, root shape, micro-thread(upper three thread).It was Korean domestic brand which was similar to Astra implant regarding appearance. Results : A population of this study was consisted of all men with average age of 68 years. Five implants of total implants failed after one month. 1. There was statistically significant difference between two implant systems at the baseline measurements(0 year) (RBM 0.479 mm vs. SLA 0.132 mm). 2. There was statistically significant difference at 1 year measurements (RBM 0.801 mm vs. SLA 0.424 mm). 3. There was statistically significant difference at 3 year measurements (RBM 1.672 mm vs. SLA 0.844 mm). 4. As the diameter became wider, the MBL of RBM was significant statistically. The MBL of SLA was not. 5. As the length became longer, the MBL of RBM was significant statistically. The MBL of SLA was not. Conclusion : Both implants were clinically acceptable. With the limitations of this study SLA surface implant showed better radiographic and clinical record than RBM surface. Key words : implants, marginal bone loss, SLA, RBM.

Book Description
PURPOSE. The marginal bone loss of implants with laser treated surface was investigated after six weeks ofloading after implant installation to the mandible molar area. MATERIALS AND METHODS. A total of 23 implants were placed in the edentulous molar area of the mandible: 13 implants were immediately loaded and10 implants were early loaded. The implants used were made of titanium grade 23, screw shaped, 4.2 mm indiameter, and 10 mm in length. Patients were evaluated with resonance frequency analysis at implant fixtureinstallation and 1, 2 (final prosthesis installation), 3, 5, 8, and 14 months later. X-rays were taken at 2 monthsafter fixture installation and 1, 2, 3 years after to measure the marginal bone loss. RESULTS. The mean ISQ valuemeasured at the implant installation was over 70 at all-time points. The average of marginal bone loss wasaverage 0.33 mm. CONCLUSION. Immediate implant loading for laser treated implants would be possible.

Book Description
Abstract:Background: The aim of this study was to assess the clinical and radiographic outcome of a new, bone level tapered dental implant with a hydrophilic surface when inserted either following an immediate or early placement protocol. Furthermore, the behavior of the implant stability quotient (ISQ) at different time-points and the aesthetic outcome was analyzed.Material and methods: Patients in need of tooth extraction and replacement by a single implant in the anterior to premolar areas of their maxillae or mandibles were recruited. The patients were randomly assigned to either the immediate or the early placement group. 4-6 weeks after implant placement, the impression was performed. 8-10 weeks after surgery, the implants were loaded with the final crown. The clinical and radiological outcomes were assessed. Furthermore, the behavior of the implant stability quotient at different time-points and the aesthetic outcome was analyzed.Results: All 20 implants could be loaded according to the protocol within 8-10 weeks after implant placement. At the 12 months follow-up visit, all 20 implants were osseo-integrated and the survival rate was therefore 100%. The ISQ values of all 20 implants showed a trend towards a gradual increase from 69.6 (buccal) and 72.7 (mesial) directly after implant placement to 73.55 (buccal) and 76.2 (mesial) at impression taking and 75.95 (buccal) and 78.4 (mesial) at loading. During the follow-up visits, the mean distance from implant shoulder to the first bone-to-implant contact was 0.32 mm after 6 months and 0.35 mm after 12 months, respectively. At the 12-months examination, the mean bone loss in the immediate group was 0.55 mm and 0.18 mm in the early placement group.Conclusions: The short-term, preliminary data of this clinical study demonstrate high survival rates and excellent clinical outcomes. Bone level tapered implants placed by means of both immediate and early implant placement protocols exhibit similar survival and success rates, changes in the crestal bone level and esthetic outcomes 12 months after loading.
