Survival rates and stability of OSP and OSPTX implants was comparable. Osteotomy preparation either by the standard or by the soft bone surgical protocol had no significant effect on implant survival, success, and stability. Insertion torque presented a moderate to strong correlation with ISQ values at 6 weeks, 6 months, and 1 year. Insertion torque presented a weak correlation to ISQ values...

Insertion torque presented a moderate to strong correlation with ISQ values at 6 weeks, 6 months, and 1 year but not at time of implant insertion. This finding is in agreement with Acil et al. who reported no statistically significant correlation between insertion torque and ISQ at time of implant placement [22]. Although a strong correlation was found between insertion torque and bone loss at...

Augmentation of the maxillary sinus prior to dental implant placement is routinely performed in order to help patients restore their maxillary posterior dentition. Unfortunately, not all patients are candidates for this procedure due to either health, personal, or financial concerns. An alternative treatment without the need for a sinus elevation procedure is the use of a shorter implant. Research...

Overall implant survival rate was 93.3%. Two implants failed, one implant in group A (OSPTXSoft) and one in group B (OSPTXStd). Both implant failures occurred at the time of uncovery (at 6 weeks) and prior to loading of the implants and were attributed to lack of integration. With the exception of these two failed implants, there was 100% success for all remaining implants using the parameters de...

ANOVA was used to compare the mean implant stabilities between the three groups. Post hoc testing was done via Tukey’s honestly significant differences test to calculate the differences between ISQ measurements at the time of implant placement, 6 weeks and 6 and 12 months (Fig. 2) as well as bone levels at 6 and 12 months (Fig. 3).

A recent systematic review by Stocchero et al. concluded that an undersized drilling protocol in soft bone is an effective way to enhance insertion torque but recommended that further clinical studies are needed to confirm these data [18]. Our study was designed to address this question, as it compared the standard drilling protocol to a soft bone protocol. Our study hypothesis is that the stabil...

Dental implants are now a widely accepted treatment option for the replacement of missing teeth. The therapeutic goal of dental implants is to support restorations that replace single or multiple missing teeth so as to provide patient comfort, function, and esthetics as well as assist in the ongoing maintenance of remaining intraoral and perioral structures. However, anatomic limitations such as t...

The purpose of this study was to compare a parallel wall design implant to a tapered apex design implant when placed in the posterior maxilla using two different surgical protocols. Twenty-seven patients (30 implants) were divided into three groups. All implants were 4 mm wide in diameter and 8 mm long. Group A received 10 tapered implants (OSPTX) (Astra Tech OsseoSpeed TX™) using the soft b...

Survival rates and stability of OSP and OSPTX implants was comparable. Osteotomy preparation either by the standard or by the soft bone surgical protocol had no significant effect on implant survival, success, and stability. Insertion torque presented a moderate to strong correlation with ISQ values at 6 weeks, 6 months, and 1 year. Insertion torque presented a weak correlation to ISQ values...

Insertion torque presented a moderate to strong correlation with ISQ values at 6 weeks, 6 months, and 1 year but not at time of implant insertion. This finding is in agreement with Acil et al. who reported no statistically significant correlation between insertion torque and ISQ at time of implant placement [22]. Although a strong correlation was found between insertion torque and bone loss at...

Augmentation of the maxillary sinus prior to dental implant placement is routinely performed in order to help patients restore their maxillary posterior dentition. Unfortunately, not all patients are candidates for this procedure due to either health, personal, or financial concerns. An alternative treatment without the need for a sinus elevation procedure is the use of a shorter implant. Research...

Overall implant survival rate was 93.3%. Two implants failed, one implant in group A (OSPTXSoft) and one in group B (OSPTXStd). Both implant failures occurred at the time of uncovery (at 6 weeks) and prior to loading of the implants and were attributed to lack of integration. With the exception of these two failed implants, there was 100% success for all remaining implants using the parameters de...

ANOVA was used to compare the mean implant stabilities between the three groups. Post hoc testing was done via Tukey’s honestly significant differences test to calculate the differences between ISQ measurements at the time of implant placement, 6 weeks and 6 and 12 months (Fig. 2) as well as bone levels at 6 and 12 months (Fig. 3).

Dental implants are now a widely accepted treatment option for the replacement of missing teeth. The therapeutic goal of dental implants is to support restorations that replace single or multiple missing teeth so as to provide patient comfort, function, and esthetics as well as assist in the ongoing maintenance of remaining intraoral and perioral structures. However, anatomic limitations such as t...

Conclusions : Impact of surgical management in cas...

In conclusion, and within the limits of its retrospective nature, our study implies that in cases of intraoperative perforation of the Schneiderian membrane, a consequent surgical assessment and treatment might avoid complications regarding graft stability and implant survival. Two-stage procedures might be appropriate if primary stability does not seem to be achievable. Augmentation of the sinus ...

Discussion : Impact of surgical management in case...

The surgical management in cases of a membrane perforation might also influence the overall postoperative outcome and complications. Although the sinus lifting procedure has been established for many years now, there are no evidence-based guidelines for perforation closure or indications to interrupt the procedure. To date, most existing studies recommend sealing smaller sizes of perforations with...

One implant was lost in the perforation group due to early-onset peri-implantitis, whereas all implants in the control group were still in place. As we had previously prospectively reported on the first 6 months after dental implantation in this cohort [11], there was no further impact of membrane perforation on implant loss for at least 12 to 24 months in this retrospective evaluation. The appe...

The aim of this retrospective cohort study was to evaluate the impact of intraoperative perforations of the Schneiderian membrane during sinus floor elevation on the stability of the augmented area and its influence on osseointegration after implant insertion. Therefore, we could re-assess a patient cohort of originally 34 patients with 41 perforations and compare their outcome with a control grou...

Background : Impact of surgical management in case...

Sinus floor elevation procedures have become a predictable and successful treatment, performed when the maxillary alveolar ridge is atrophied and the bone height is not sufficient for primary implantation. If the postoperative course remains uneventful, the outcome is highly predictable [1,2,3]. However, complications may have a negative impact on the overall treatment success. As a common complic...

Abstract : Impact of surgical management in cases ...

Until now, sinus floor elevation represents the gold standard procedure in the atrophic maxilla in order to facilitate dental implant insertion. Although the procedure remains highly predictive, the perforation of the Schneiderian membrane might compromise the stability of the augmented bone and implant success due to chronic sinus infection. The aim of this retrospective cohort study was to show ...

Six of these studies (Schultes et al., Wang et al., Zou et al., Chiapasco et al., Chiapasco et al., Wu et al.) reported some of this lack of success to the peri-implant soft tissue which was most frequently the soft tissue component of a combined bone and soft tissue free flap (most commonly the external skin). Complications A variety of implant-based complications were documented. Complicatio...

Autogenous bone graft type and implant survival Seventeen studies reported on the specific bone graft type (non-vascularised or vascularised) into which the implants were placed. In the remaining three studies (Buddula et al., Fierz et al., Yerit et al.), this distinction was not possible. Of these 17 studies, 8 studies reported on implant survival in non-vascularised bone grafts and 14 studie...

Introduction : Survival of dental implants placed

Introduction Rationale The use of implants to retain prostheses as part of oral and dental rehabilitation of head and neck (H&N) cancer patients is becoming an increasingly common treatment approach. A number of benefits advocating implant anchorage over conventionally secured prostheses have been proposed but importantly include a significant improvement in the reported quality of life (QoL) of...

Abstract Dental implant surgery has developed to a widely used procedure for dental rehabilitation and is a secure and predictable procedure. Local and systemic risk factors can result in higher failure rates. Diabetes mellitus is a chronic disease that goes in with hyperglycemia and causes multifarious side effects. Diabetes as a relative contraindication for implant surgery is controversially...

Discussion Augmentation of the maxillary sinus prior to dental implant placement is routinely performed in order to help patients restore their maxillary posterior dentition. Unfortunately, not all patients are candidates for this procedure due to either health, personal, or financial concerns. An alternative treatment without the need for a sinus elevation procedure is the use of a shorter...

Results Overall implant survival rate was 93.3%. Two implants failed, one implant in group A (OSPTXSoft) and one in group B (OSPTXStd). Both implant failures occurred at the time of uncovery (at 6 weeks) and prior to loading of the implants and were attributed to lack of integration. With the exception of these two failed implants, there was 100% success for all remaining implants using the par...

To avoid invasive sinus augmentation procedures, implants have been designed in shorter lengths such as 8 mm. To further enhance short implant primary stability, a tapered design has been developed which has been proven to provide greater initial stability. Implant stability can be evaluated by different measures such as torque at the time of implant placement, resistance to reverse torque, and re...

Background Dental implants are now a widely accepted treatment option for the replacement of missing teeth. The therapeutic goal of dental implants is to support restorations that replace single or multiple missing teeth so as to provide patient comfort, function, and esthetics as well as assist in the ongoing maintenance of remaining intraoral and perioral structures. However, anatomic limitat...
