Review Meta AnalysisInterventions for replacing missing teeth: 1- versus 2-stage implant placement.
Implants may be placed penetrating the oral mucosa (1-stage procedure) or can be completely buried under the oral mucosa (2-stage procedure) during the healing phase of the bone at the implant surface. With a 2-stage procedure the risk of having unwanted loading onto the implants is minimized, but a second minor surgical intervention is needed to connect the healing abutments and more time is needed prior to start the prosthetic phase because of the wound-healing period required in relation to the second surgical intervention. ⋯ The number of patients included in the trials was too small to draw definitive conclusions. The 1-stage approach might be preferable in partially edentulous patients since it avoids one surgical intervention and shortens treatment times, while a 2-stage submerged approach could be indicated when an implant has not obtained an optimal primary stability or when barriers are used for guided tissue regeneration, or when it is expected that removable temporary prostheses could transmit excessive forces on the penetrating abutments especially in fully edentulous patients.

ReviewWITHDRAWN: Orthotic devices after stroke and other non-progressive brain lesions.
Post-stroke motor impairments cause difficulty controlling the joints of the affected limbs to produce useful movements. One way to manage this to use an orthosis to control the movement of the affected joints but evidence for their benefit is lacking. ⋯ A lower limb orthosis can improve walking and balance but the included studies have only examined the immediate effects while wearing the orthosis; the effects of long-term use have not been investigated. An upper limb orthosis does not effect on upper limb function, range of movement at the wrist, fingers or thumb, nor pain, but this conclusion is based on only three trials.
