Correction: Peri-implant behavior of sloped shoulder dental implants used for all-on-four protocols: An histomorphometric analysis in dogs [Materials, 11, (2018), (119)]doi 10.3390/ma11010119

The aim of this study was to evaluate the soft tissue thickness and marginal bone loss around dental implants with sloped micro-threaded shoulder (30° angle) in comparison to conventional design, inserted 30° angulated in post extraction sockets and immediately loaded with temporary prosthesis simulating the all-on-four protocol. Materials and Methods: Six fox hound dogs received forty-eight post extraction dental implants with the different diameter . . . In "4. Materials and Methods", authors change 35° to 30°, "Medentika™" to "Quattrocone Medentika", "with 3.5 mm diameter and 9 mm length" to "with 3.5 mm diameter by 9 mm length for Quattrocone straight implants and 4.3mmdiameter by 9mmlength for Quattocone30 dental implants". The correct expressions are given as: Surgical guide with four orifices (two axial (0°) and two inclined at 30°) were anchored with intraosseous pins to the cortical bone and a guided drilling protocol was used for the osteotomies (Figure 2). Forty-eight Medentika™dental implants (Medentika GmbH, Hügelsheim, Germany) with 3.5mm diameter by 9 mm length for Quattrocone straight implants and 4.3 mm diameter by 9 mm length for Quattrocone30 dental implants with two different designs were inserted inside extracted distal roots (both straight and sloped implants), divided into two groups (n = 24 per group): the Control group used a conventional implant design with axial micro threads; the Test group used sloped implants with 30° angle and micro threads (Figure 3).
