[Analysis of clinical effects and risk factors of short implant followed up for 7-9 years].

PURPOSE: To evaluate the long-term clinical efficacy of short implants and analyze the influencing factors of the survival rate. METHODS: A total of 178 patients who received implant therapy in the Department of Stomatology, the Fourth Affiliated Hospital of Nanchang University from January 2010 to December 2014 were selected, including 334 short implants of Bicon (implant length ≤6 mm). The basic condition, restoration design, short implant survival rate and complications were observed and analyzed. SPSS 24.0 software package was used for data analysis. RESULTS: The average follow-up time of short implants was 96±17 months. During the observation period, 20 implants failed, 1 implant had mechanical complications and 6 implants had biological complications. Based on the analysis of implants and patients, the long-term cumulative survival rate of short implants was 94.0%(over 5 years survival rate was 96.4%) and 90.4% respectively. There was no significant difference between the survival rate of short implants and the patient's gender, age, whether to use special operation and the type of jaw teeth(P＜0.05). Smoking and periodontitis were risk factors for failure of short implants(P＜0.05).The difference of short implant survival rate between short implants restoration with combined crowns and single crowns was statistically significant(P＜0.05). The survival rate of short implant in mandible was higher than that in maxilla(P＜0.05). CONCLUSIONS: Under the standards clinical program and operation, short implant can be used to shorten the implant restoration cycle and avoid complicated bone augmentation which can achieve good long-term clinical effect. Short implant should be used to strictly control the risk factors that affect the survival of short implant.

Displacement of the full body of a dental implant into the sinus space without membrane perforation and subsequent osseointegration: a case report.

An increasing number of studies have investigated the use of osteotome sinus floor elevation (OSFE) with simultaneous implant placement for maxillary sinus floor residual bone height (RBH) <4 mm. Many studies have reported good clinical results, but very few have reported complications related to this procedure. Here, the case of a 50-year-old female patient with an RBH in the left upper posterior region of 1-4 mm, who underwent OSFE with simultaneous placement of three Bicon short® implants, is described. One of the implants was found to be displaced during the second-stage surgery. The displaced implant was removed using piezosurgery, OSFE with simultaneous implant placement was repeated, and the missing tooth was reconstructed 6 months later. This case suggests that OSFE with simultaneous implant placement is feasible for severely atrophic maxillary sinus floor, but carries a risk of implant displacement.

[Retrospective study on transcrestal sinus floor elevation with simultaneous implantation of short implants].

OBJECTIVE: To explore the changes in bone height of the maxillary sinus floor at different sinus ridge heights after transcrestal sinus floor elevation (tSFE) with the simultaneous implantation of short implants. METHODS: A total of 74 Bicon short implants were implanted into 37 patients during the same period of maxillary sinus elevation. The residual bone height (RBH)<4 mm group has 43 sites, and the RBH≥4 mm group has 31 sites. After 5 years of follow-up observation, the implant survival rate and the change in bone height achieved in the maxillary sinus over time were measured and analyzed via clinical examination and X-ray imaging. RESULTS: In the 74 implantation sites, the elevation height of the sinus floor was (6.64±1.32) mm and the bone height of the sinus floor was (3.35±1.29) mm 5 years after loading. No statistical difference was observed in the bone resorption of the implant neck between the RBH<4 mm and RBH≥4 mm groups. Meanwhile, a statistical difference was noted in the bone height obtained in the maxillary sinus between the two groups. CONCLUSIONS: When RBH in the maxillary posterior tooth area was <4 mm, the simultaneous implantation of Bicon short implants with tSFE can achieve a high implant survival rate and bone gain in the maxillary sinus, but does not increase the absorption of the alveolar ridge bone.

Unconventional implant strategy for patients with a limited interocclusal space in the posterior region: a case report.

BACKGROUND: Implant prostheses require sufficient interocclusal space. In cases of limited interocclusal space, reducing or extracting over-erupted opposing teeth, orthodontic intrusion, or surgical reconstruction of the edentulous space are commonly used to restore the interocclusal space. However, there are disadvantages to these approaches. CASE PRESENTATION: The present case report describes a patient with a limited interocclusal space managed using an unconventional implant strategy. CONCLUSIONS: The patient presented satisfactory outcomes without any signs of implant failure, suggesting that the unconventional implant treatment strategy is a useful option for patients with a limited interocclusal space in the posterior region. This unconventional implant surgery provides a minimally invasive treatment alternative.

Effect of Sensomotor Insole on Gait and Energy Expenditure for Children with Cerebral Palsy / 中国康复理论与实践

Objective:To evaluate the effects of sensomotor insole (SMI) on gait and energy expenditure in children with spastic cerebral palsy during walking. Methods:From December, 2014 to March, 2016, 42 children with spastic cerebral palsy aged three to 15 years were recruited. Their gait parameters and energy expenditure of six minute walking were measured under two test conditions: walking with shoes and walking with shoes and SMI. Results:After wearing SMI, the walking distance, speed, left step length and right step length were all greater (t = -6.022~-4.331, Z= -4.814~-4.183, P < 0.001), the both feet single limb support was shorter (t = 2.954, P < 0.05), and the energy expenditure was higher than before (t = -2.358, P < 0.05). Conclusion:SMI as a sort of orthopedic insole, could improve the gait parameters of children with cerebral palsy immediately after wearing it, and increase the energy expenditure slightly.

Effect of variable hip abduction orthosis on children spastic cerebral palsy / 中国康复理论与实践

@#ObjectiveTo explore the effect of variable hip abduction orthosis on children spastic cerebral palsy.Methods5 children with spastic diplegia cerebral palsy had used variable hip abduction orthosis to correct scissors gait which remained after rehabilitation. The stepping of 5 children was assessed with a gait analysis system base on digital video and image processing which could provide distance rate between knees and hips(K/I) in gait phase. One year Follow up was carried out.ResultsThere was significant difference on K/I before and after using variable hip abduction orthorsis (P<0.05).ConclusionThe variable hip abduction orthorsis can inhibit adductor muscles convulsion, improve model kinesis of scissors gait and stabilize stepping.

Clinical rehabilitation research on 90 infants with cerebral palsy / 中国康复理论与实践

@#ObjectiveTo investigate the effect of rehabilitative treatment on different groups of infants with cerebral palsy in different age, sickness extent and rehabilitative period.MethodsBy the prospective method, 90 patients from 3 to 36 months old were randomly divided into three groups including 3 to 12 months, 13 to 24 months and 25 to 36 months with 30 cases each. Every 10 cases in light, moderate and severe degrees were given rehabilitative care for 2 months and 3 months respectively. The personal ADL of every case was evaluated at the initial and the final state. The compared score was analyzed with T test.ResultsComparing the groups of different ages, there were prominent differences of treatment under the same sickness, among the light, moderate and severe degrees(P<0.01). The rehabilitative treatment effect of 3 months was better than that of 2 months. Furthermore the effect of the group of 3-12 months was better than that of 25-36 months.ConclusionsThe rehabilitative care is prominently effective in the light and moderate groups , the former is better and within 3 months is better than 2 months. The younger infant is, the better the rehabilitative treatment is.
