Title: Mini-implant mandibular overdentures under a two-step immediate loading protocol: A 4-6-year retrospective study
Authors: Park, Jin-Hong; Shin, Sang-Wan; Lee, Jeong-Yol
Abstract: Objectives
This retrospective study to evaluate the treatment outcomes of mandibular mini-implant overdentures (MIODs) placed under a two-step immediate loading protocol.
Background
The mini-implant overdenture emphasises the advantages of simplicity using flapless surgery and immediate loading. However, some mini-implant have lowe initial stability.
Materials and Methods
A total of 30 participants who used mandibular MIODs and maxillary removable complete dentures (RCDs) over 4 years were included. Four one-piece mini-implants (<3 mm in diameter) were placed by a flapless surgical approach after fabrication of new RCDs, and the O-ring attachment was attached at least 8 weeks after implant placement.
Results
The average observation period was 58.9 ± 9.2 months after mini-implant loading. The survival rate of the implants was 100.0%, and the overall change in mean marginal bone level (ΔMBL) was −0.9 ± 1.1 mm. The implant success rate was 83.3% at the implant level, and 66.7% at the patient level. The mean initial Periotest value was 0.9 ± 3.1, and it was positively associated with ΔMBL and implant success (P < .05). Patient satisfaction improved after conversion from RCDs to MIODs (P < .05), and mastication and pain showed greater satisfaction with longer loading time (P < .05).
Conclusions
The mandibular MIODs could be chosen as an alternative treatment under a two-step immediate-loading protocol in edentulous patients with limited alveolar bone volume. To ensure superior treatment outcomes of MIODs, initial stability of implant must be obtained using as wide a diameter as possible within the anatomically allowable limits.2023-12-01T00:00:00ZNarrow-diameter versus regular-diameter dental implants for mandibular overdentures: A systematic review and meta-analysis

Title: Narrow-diameter versus regular-diameter dental implants for mandibular overdentures: A systematic review and meta-analysis
Authors: Park, Jin-Hong; Shin, Sang-Wan; Lee, Jeong-Yol
Abstract: Purpose
The aim of this systematic review was to compare treatment outcomes in terms of implant survival rate, marginal bone loss, and patient-reported outcome measures (PROMs) between narrow-diameter implants and regular-diameter implants (RDIs) for mandibular implant overdentures (MIOs).
Methods
This study was based on the methodology adapted as per Cochrane. Medline, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, and Scopus were searched for pertinent studies published by July 22, 2022. Outcome parameters included in this meta-analysis were implant survival rate, marginal bone loss, visual analogue scale score for patient satisfaction, and value of oral health impact profile.
Results
A total of 782 non-duplicate articles and 83 clinical study registrations were identified from database and hand searches, of which 26 were eligible for full-text searches. Finally, 12 publications reporting on 8 independent studies were included in this review. In the meta-analysis, implant survival rate and marginal bone loss did not significantly differ between narrow-diameter implants and RDIs. Regarding RDIs, narrow-diameter implants were associated with significantly better outcomes in general patient satisfaction and oral health-related quality of life than RDIs for mandibular overdentures.
Conclusions
Narrow-diameter implants have competitive treatment outcomes compared to RDIs in terms of implant survival rate, marginal bone loss, and PROMs. [Correction added on July 21, 2023, after first online publication: The abbreviation RDIs was changed to PROMs in the preceding sentence.] Thus, narrow-diameter implants might be an alternative treatment option for MIOs in situations with limited alveolar bone volume.2023-10-01T00:00:00ZComparison of Breast Cancer and Cervical Cancer in Uzbekistan and Korea: The First Report of The Uzbekistan-Korea Oncology Consortium

Abstract: In general, as a country's economy, education level, and life expectancy increase, the incidence of cancer increases. This is because the peak incidence of cancer occurs in individuals in their 70s and 80s, and the health proportion of non-communicable diseases increases with the development of the living environment. Changes in diet, lifestyle and enhanced methods of detection contribute to an increase in cancer incidence as well. Recently, Uzbekistan has grown rapidly, and its incidence of cancer is also increasing. In the health management of cancer, not only treatment but also the identification and prevention of causes and effective screening should be considered. South Korea has a common ethnicity with Uzbekistan and has successfully performed national screening for seven major cancers over the past 20 years. The 5-year survival rate after cancer diagnosis in Korea was only 42.9% 20 years ago, but recently it has improved to 70.7%. We formed an advisory consortium in which oncologists from Uzbekistan and Korea could cooperate for cancer management in Uzbekistan. This advisory consortium intends to present the necessary considerations and recommendations for cancer management in Uzbekistan by examining the literature and cancer statistics of Uzbekistan and South Korea. In addition to the overall analysis, we identified and reviewed the major cancers with high morbidity in three categories in Uzbekistan: gynecological cancer (breast and cervical cancer), cancer common in men (lung and liver cancer), and gastrointestinal cancer (stomach and colorectal cancer). This review covers the general cancer statistics of Uzbekistan and a detailed review of gynecological cancer between two countries, and relevant recommendations.2022-10-01T00:00:00ZChallenges and Suggestions in Management of Lung and Liver Cancer in Uzbekistan: The Second Report of the Uzbekistan-Korea Oncology Consortium

Abstract: The health burden of cancer increases in Uzbekistan as the country develops and the life expectancy increases. Management of such a burden requires efficient screening, treatment optimization, and investigation of the causes of cancer. The Ministry of Health of Uzbekistan formed an advisory consortium, including clinical oncology and healthcare management experts from Uzbekistan and South Korea, to design a strategy for cancer management. Our consortium has analyzed six cancer types with high morbidity and mortality in Uzbekistan by classifying them into three categories (breast, cervical (gynecologic cancers), lung, liver (cancer common in men), stomach, and colorectal cancers (gastrointestinal cancers)). Lung and liver cancers are common causes of death in men after middle age-they can yield a serious health burden on the country and ruin the livelihood of families. In this review, we will analyze the oncologic literature and suggest practical recommendations for the treatment and prevention of lung and liver cancer in Uzbekistan. Data from South Korea, which has conducted nationwide screening for two decades and made progress in improving prognosis, will be discussed as a comparative control.2022-09-01T00:00:00Z
