“…The greater retention provided by the SIO is probably responsible for our increased opening and closing velocities. This finding is in accordance with a recent kinesiograph study that showed improved on vertical opening of elderly participants rehabilitated with SIO prostheses after 3 months of use (25).…”

The use of two-implant overdentures improves mastication of edentulous elderly patients. However, little is known about the effects of single-implant overdentures (SIO) on oral perception and masticatory function in such elders. This study compared the effects of conventional complete dentures (CD) and SIO on the oral sensorimotor ability (OSA), masticatory function, and nutritional intake of elderly people with residual alveolar mandibular height classified as Class III or IV according to the American College of Prosthodontics. Twelve elders first received new conventional CD, which were later converted to SIO. All variables were evaluated after use of each prosthesis for 2 months. To evaluate OSA, elders closed their eyes and orally identified test pieces prepared from raw carrots. A kinesiographic device was used to measure chewing movements during mastication of a test material (Optocal). Masticatory performance (MP) was determined with the sieving method, and a 3-day food diary verified nutrient intake based on a standard Brazilian Food Composition Table. Data were analyzed using the Wilcoxon signed rank test and Student's paired t test (P < 0.05). OSA results did not differ according to prosthesis type. However, opening and closing velocities during chewing and MP increased after SIO insertion (P < 0.05). Although no difference was observed in the intake of most nutrients, sodium ingestion decreased after SIO insertion (P < 0.05). SIO use had no effect on OSA, but significantly improved mastication and sodium intake of elders with decreased residual ridges height (Brazilian Registry of Clinical Trials #RBR-3kgttj).

“…In the past decades, two-implant retained overdenture is considered as the first choice for treatment for patients with edentulous mandibles that were poorly adapted to conventional dentures (1,2). However, many patients refused this treatment modality due to their fear from surgical procedures (3)(4)(5). Moreover, this treatment remains inaccessible for patients with poor socio-economic conditions, and higher surgical risks due to impaired health conditions (6)(7)(8).…”

“…Current evidence-based studies (7)(8)(9)(10) and randomized controlled trials (RCTs) (3,4,11,12) showed that retaining the existing mandibular denture by a single midline implant might be considered as a potential alternative treatment for completely edentulous patients. Cordioli et al used delayed loading protocol and ball attachment with 100% implant survival rate after 5 years (13).…”

“…Single-implant mandibular overdenture (SIMO), when opposed with maxillary denture, exhibited good results in comparison with two-implants-retained denture. This can be clinically interpreted by survival rates, clinical parameters, improved patient's satisfaction and quality of life (4,5,9,12,14). The favorable bone quality in the symphysis region and, the inferior alveolar neuromuscular bundles, would simplify the surgical procedure, this is an advantage to the clinicians (14).…”

“…On the contrary, several laboratory studies reported that SIMO-retained with ball attachments could move and slide on the mucosa in various directions that could increase the concentration of stresses around the housing portion of the single implant during function (23,24). This compromised denture stability might negatively influence the implant stability of the immediately loaded implants, resulting in more implant failures (3,4,25).…”

Aim: The aim was to evaluate the efficacy of attachment placement on initial stability and bone height changes for immediately loaded single-implants retaining mandibular overdentures. Methodology: Twenty edentulous patients were recruited for this study; 9 females (45.0%) and, 11 males (55.0%) (age ranged from 59.0 to 70.0 year). Single endoosseos implant was inserted in the mandibular midline region. Immediately after surgery; Locator abutment was secured on the implant and the male housing was connected intraorally using direct pick-up procedure. Marginal bone height measurements and implant stability values were assessed at the time of implant placement (baseline), 2,4,6,8, 12, 24 weeks then every 6-month interval up to 18 months post-implant placement. Results: The implant stability values decreased markedly from the baseline, during 4 weeks and, then increased gradually until reaching the initial values after 12 weeks followed by continuous increase to study’s end (p<0.05). The peri-implant marginal bone level revealed an acceptable range of bone loss with a statistically signiﬁcant differences between different follow-up times and it continued to the end of the study (p<0.05). Conclusion: Retaining an overdenture by immediately loaded single implant could be a successful treatment option for mandibular edentulous arches, especially in people with limited financial resources. The use of Locator attachment seemed to have a favorable effect on implant stability and marginal bone around immediately loaded single implant mandibular overdenture after 18-months of function.

A Randomized Clinical Trial of Oral Health‐Related Quality of Life, Peri‐Implant and Kinesiograph Parameters in Wearers of One‐or Two‐Implant Mandibular Overdentures

Abstract: This study suggested that 1-IOD can improve patient OHRQoL and may be similar to 2-IODs in preservation of both peri-implant parameters and masticatory movements.
