ObjectiveThe aim was to compare esthetic outcomes, masticatory performance and a comfort of removable partial denture (RPD) wearing after receiving: clasp-retained RPD (C-RPD) or mini dental implant-retained RPD (MDI-RPD) in the mandible.Materials and MethodsA sample of 88 patients (Kennedy Class I) with all posterior teeth missing and a linear support for a RPD participated. A total of 52 patients (36 females, 16 males; 56 to 84 years old) participated in the C-RPD group and 36 patients (26 females, 10 males; 43 to 81 years old) in the MDI-RPD group. All MDIs were placed adjacent to the last remaining mandibular anterior tooth or one tooth length posteriorly. The new RPDs had Co-Cr frameworks with lingual plate major connectors; the MDI-RPDs were retained by O-ball matrices and the C-RPDs with clasps. Patients answered questions at pre-treatment and post-treatment stages and after 6-months follow-up: how satisfied they had been with esthetic appearance, how confident they were while chewing hard food, how satisfied they were with food comminution and they also evaluated a comfort of RPD wearing. The 0-10 visual-analogue scale was used. Statistics included descriptive methods, t-tests and the standardized effect-size calculation.ResultsThe MDI-RPD wearers were more satisfied with their post-treatment esthetics, food comminution, a comfort with RPDs and had better confidence while chewing than the C-RPD wearers. The MDI-RPD wearers reported larger positive effect of the treatment. The results were consistent throughout the first 6-months period.ConclusionThe MDI-RPD patients showed superior outcomes than the C-RPD patients after the treatment and over the 6-month period.

Operations undertaken for inguinal hernia repair are the most common elective surgical procedures. According to the current guidelines, Lichtenstein's tension-free method is the gold standard for elective hernia operations. The most common types of implanted mesh are polypropylene and composite mesh. We herein present Lichtenstein's operation using a biological hemostatic mesh (Tachosil) used for transversalis fascia reinforcement, and our results after a 3-year follow-up period for 52 patients implanted with Tachosil mesh are reported. According to our results, the biological mesh can be safely implanted during hernia repair with the same recurrence rate and lower postoperative pain and complications compared to hernia repair with polypropylene mesh implantation.

The reason for this transition is simple: many procedures can be executed more efficiently and with less morbidity using lasers when compared with scalpel, electrocautery or high frequency devices. Onisor [12] performed an in vitro study using Er: YAG and CO 2 laser for crown lengthening, gingivoplasty and maxillary labial frenectomy. The same authors [12] concluded that Er: YAG is able to provide good cutting and coagulation effects on soft tissues. Specific parameters have to be defined for each laser in order to obtain the desired effect. Reduced or absent water spray, defocused light beam, local anesthesia and use of long pulses are important in order to obtain optimal coagulation and bleeding control. Kaya [13] described a case of pyogenic granuloma around an implant seven years after its insertion which they treated by use of Er: YAG laser. Türer [14] compared Er: YAG laser to the scalpel in the preparation of the recipient site for free gingival grafts. The same authors [14] stated that Er: YAG laser may be used with similar effectiveness as the scalpel for this purpose. Laser surgery has emerged as an established method in advanced medicine. Laser-induced remote tissue treatment provides a number of advantages: controllable coagulation and cutting of surgical tissues with wavelength tissue-specific cutting efficiency [15].
