Introduction Contusive trauma or malocclusionrelated periodontal disease can severely compromise the upper anterior teeth, leading to labial bone resorption and ultimately loss of function and unsightly root exposure. To resolve these issues, we propose the replacement of compromised teeth using one-piece, immediateload, post-extraction implants. These can be implanted and fitted with customised temporary crowns in a single surgical procedure, restoring function and aesthetics and allowing recovery of the bone deficit with reduced healing times and limited patient discomfort. This study aims to assess the one-piece, immediateload, post-extraction implants in labial bone-deficient upper jaws. Materials and methods One-piece, wide diameter, titanium screw implants with thread measurements of 3.5 mm and 4.5 mm, with an abutment of 2.5 mm, were positioned and splinted by intraoral welding. Results These implants yielded satisfactory functional and aesthetic outcomes in bone-deficient upper anterior sectors, without invasive regenerative procedures. Conclusion The low invasiveness of the approach used in this research study consents rapid healing, reduced biological burden and greater patient benefit.
Despite initial enthusiasm, blade implants have received bad press over the years due to fairly high failure rates reported in some publications of non-users. Materials and methods A total of 522 blades were inserted in 20 years (1989-2009). 309 in females and 213 in males. The median age was 59 ± 11 (min-max 24-80 years). The implants were inserted in deep and atrophic narrow crests. Results Success rate was 93.4 % (488/522) globally, 98.9 % (369/373) at 5 years, 89 % (261/293) at 8 years and 86.2 % (200/232) at ten years. These data show very good results at five years, but slightly more failures at eight and ten years. Conclusion The blade implant is a valid therapeutic device useful for treating cases such as narrow bone crest and scarce spongy bone in the lower distal sector. They have been demonstrated longterm survival. Nonetheless, to prevent failure, practitioners should know that blade implants are not indicated in wide alveolar crests, or in areas where bone density is insufficient and the implant cannot be positioned in the deep cortical layer.
of the bone around the implants was observed. Conclusion Titanium needle impla nts can be used with immediate load ing in the posterior atrophic sector, especially in the elderly people, in the zone below the maxillary sinus, in the upper front area. They also give stability to other implants. In all cases, intraoral welding is necessary and requires specific clinical train ing. Needle implants are not suitable for deep and wide ridges containing dense spongy bone. The mandrel is provided with two grooves through which the fins of the needle enter. The mandrel is avail able in different sizes and lengths.
