“…According to conventional protocols, implants should not be loaded throughout the osseointegration phase, typically lasting 3‒4 months for the mandible and 6‒8 months for the maxilla. 9 , 10 Bone healing increases the contact between the implant and the surrounding bone after insertion. An implant may fail if loaded before this contact reaches a particular point.…”

<strong data-sider-select-id="db762fef-c999-47e9-9451-cf1efb55563a">Background. Modifying the dental implant’s surface texture enhances its biological response to the bone and implant‒tissue interface, resulting in the successful support of forces. This study assessed the impact of sandblasting, sandblasting plus acid etching, Er,Cr:YSGG laser, and propolis implant surface treatments and occlusal load on the osseointegration of titanium dental implants in dogs. <strong data-sider-select-id="491b6d14-e639-433f-9f28-4c5f7549e85a">Methods. Seventy-two titanium dental implants with a diameter of 4 mm and a length of 10 mm were divided into four groups according to implant surface modifications (n=18 for each group): group A: sandblasting plus acid etching, group B: sandblasting with Al2 O3 , group C: Er,Cr:YSGG laser, group D: propolis coating. Twenty-four local breed male dogs were used. Premolar teeth (P1, P2, and P3) were extracted on the left side of the mandible, and after 12 weeks of bone healing, implants were unilaterally installed. The osseointegration at three study times from implant installation (14, 90, and 180 days) was evaluated. The dog jaws were scanned using an intraoral scanner for the virtual design of screw-retained three-unit crowns after 90 days of osseointegration. Final radiographs were taken before the animals were sacrificed at 14, 90, and 180 days, and the histological analysis was performed. <strong data-sider-select-id="58f5e1a3-d137-4c81-aaf5-58b34e3196c0">Results. Radiographic analysis showed new bone formation (NBF) along and in contact with the implant surface of the treated groups. The histological analysis after 14 days in groups A and B revealed a uniform and ongoing pattern of bone growth and many osteoblasts with few osteocytes within lacunae in new bone trabeculae. Group C showed an increase in the number of osteoblasts lining thin bone trabeculae. Group D showed a generative power concerning bone. At 90 days, there was increased bone ingrowth, and the new bone matured in all the treated implant groups. At 180 days, dense mature bone apposition was in direct contact with delayed-loaded implant surfaces. <strong data-sider-select-id="fec6857b-61c7-41fd-8786-2318861f18f2">Conclusion. A radiographic examination revealed that surface modification significantly impacted osseointegration, with a strong bond between the implant surface and the surrounding bone. The histological sections at the 14-day interval revealed obvious bone remodeling activity, especially in sandblasting plus acid etching and sandblasting-modified implant surface groups. At the 90-day interval, bone ingrowth had increased, and the new bone became mature, especially in sandblasting and propolis surface modification groups. After 180 days of the delayed-loaded implant osseointegration, differences were observed between different implant-treated groups with a remarkable remodeling of the bone, especially in the propolis coating group.

Background: This study aimed to report the outcomes of the immediate loading of implants with fixed rehabilitations in edentulous geriatric patients. Methods: Edentulous geriatric patients were diagnosed with an oral examination, radiographic evaluation, and intermaxillary relations and treated with fixed rehabilitation over several implants. After immediate surgery, the implants were immediately loaded with a fully fixed prosthesis. Results: Twenty-four patients (20 females and 4 males) were treated using a total 210 implants. All patients (100%) had a previous history of periodontitis. Eleven patients (45.8%) were smokers. Eleven patients (45.8%) suffered from chronic medical diseases (i.e., diabetes, cardiovascular diseases). The study’s clinical follow-up period extended for three years, during which thirty-three fixed prostheses were installed over the implants in 24 patients. The average marginal bone loss measured was 1.33 ± 0.17 mm. The success rate of the implants and prosthodontics being placed in this study yielded 98.5% and 97%, respectively. One patient (4.2%) showed some kind of technical complications. Eleven patients (45.8%) showed mucositis, and 25 implants (11.9%) in 10 patients (41.7%) were associated with peri-implantitis. Conclusions: This study shows that the treatment of edentulous geriatric patients by immediate loading of implants with fixed rehabilitations is a clinically successful protocol but with a high prevalence of peri-implant diseases.

Mandibular Overdentures When Treating Failing Dentition With Immediate Prosthetic Loading

Patients may present with failing mandibular dentition either involving the entire arch, partial arch that currently has a partial denture to replace the prior missing teeth or wearing a full denture. Finances may limit restoration of the arch with an All-on-X concept and the patient's goals are a stable prosthesis that does not move whenconcept and the patient's goals are a stable prosthesis that does not move when eating or speaking is the patient's expressed goal. Overdentures can fulfil that goal and provide a stable restored arch at a lower treatment cost than treatment with a fixed hybrid prosthesis. Traditionally, when these type cases have been treated, the remaining dentition has been extracted, depending on availability of bone, implants are placed. Those typically were left to osseointegrate and loaded several months later with a delayed loading approach. This requires relining the denture and the patient having a loose, non-stable prosthesis during that healing phase. An alternative approach utilizes immediate activation of the implants with overdenture attachments thus, providing an immediate stable retentive full arch mandibular removable prosthesis (overdenture) by immediate activation of overdenture attachments (ie.Locators) aids the patient in their goals without delays in treatment. This article will present two case examples of mandibular arches with failing dentition related to caries and periodontal issues and their treatment with immediate implant placement and loading with Locator attachments. Long-term follow-up of 1-year 8-months in one case and 33-months in the other case demonstrate crestal bone stability with this immediate overdenture loading protocol.
