Maxillary Overdentures Supported by Four Splinted Direct Metal Laser Sintering Implants: A 3-Year Prospective Clinical Study

Figure 1

Macroscopical and microscopical features of the direct metal laser sintering (DMLS) titanium implants used in this study: the implants had an external hexagon connection (a); the scanning electron microscopy of the implant (1700) showed a porous surface with ridge-like and globular protrusions, interspersed by intercommunicating pores and irregular crevices (b).
