Comparative studies of a traditional dental surgical treatment and a CO2 laser technique with regard to the subjective feelings of patients

On the basis of the accomplished observations of 113 patients treated in the Department of Oral Surgery in Wroclaw’s Medical University in the years 2009–2011, the authors stated that the use of CO2 laser as cutting instrument is a good method due to the clinical features as well as a positive feeling of patients. Surgical laser operations in patients opinion are painless. The post procedural period is also painless. According to the patients the short time of the surgical procedure is an advantage of this method. The level of fear before treatment is not associated with the surgical treatment method but rather with extent of the procedure. Patients treated by CO2 laser declared that before another such operation they would feel less afraid

Orthodontic and orthodontic-surgical management of impacted canines – a literature review

The phenomenon of impacted canines is observed in about 0.8–4.9% of patients treated orthodontically. In 85% of cases it is observed unilaterally. Besides the third molars, canines are the largest group of impacted teeth. The impacted tooth diagnosis includes clinical and radiological examination. In this particular case, the screening test is a pantomographic X-ray. The full picture of the location of an impacted tooth and adjacent structures can be obtained only through the use of computed tomography. Only a full diagnosis allows a decision to be made as to the treatment of impacted canines and permits an evaluation of the possibility of treatment success. In the case of impacted teeth, the procedures may be varied. Mostly, the tooth is either left in the bone or tracked orthodontically. Rarely is it extracted. In some cases, the surgical procedure includes the autotransplantation of the impacted tooth

The Influence of the Crown-Implant Ratio on the Crestal Bone Level and Implant Secondary Stability: 36-Month Clinical Study

Introduction. When the era of dental implantology began, the pioneers defined some gold standards used in dental prosthetics treatment for implant-supported restorations. Referring to traditional prosthetics, it was taken for granted that the length of an implant placed in the alveolar bone (the equivalent of the root) should exceed the length of the superstructure. Aim of the Study. The aim of the study was to determine whether implant length and the crown-to-implant (C/I) ratio influence implant stability and the loss of the surrounding marginal bone and whether short implants can be used instead of sinus augmentation procedures. Material and Methods. The patients participating in the study (n=30) had one single tooth implant, a short (OsseoSpeed™ L6 Ø4 mm, Implants) or a regular implant (OsseoSpeed L11 and L13 Ø4 mm, DENTSPLY Implants), placed in the maxilla. The evaluation was based on clinical and radiological examination. The crown-to-implant ratio was determined by dividing the length of the crown together with the abutment by the length of the implant placed crestally. Mean crown-to-implant ratios were calculated separately for each group and its correlation with the MBL (marginal bone loss) and stability was assessed. The authors compared the correlation between the C/I ratio values, MBL, and secondary implant stability. Results. Positive results in terms of primary and secondary stability were achieved with both (short and conventional) implants. The MBL was low for short and conventional implants being 0.34±0.24 mm and 0.22±0.46 mm, respectively. No significant correlation was found between the C/I ratio and secondary stability as well as the C/I ratio and the marginal bone loss. Conclusions. Short implants can be successfully used to support single crowns. The study has revealed no significant differences in the clinical performance of prosthetic restorations supported by short implants. Clinical trial registration number is NCT03471000
