Abstract

Gradual bone loss around the implants is an ongoing concern. Mucosal tissue thickness is considered as a contributing factor that influences bone remodelling after implantation. It has been suggested that tissue thickness thinner than 2.5 mm may contribute to more peri-implant bone loss, eventually affecting implant bone stability. Measuring mucosal thickness prior to surgery may be a predictor of the bone changes and could modify the surgical methods. In this study mucosal tissue thickness was measured retrospectively on radiographs before implant insertion, one year and at least three years after implantation. Within the limits of this study, no influence of initial mucosal tissue thickness on long term peri-implant bone stability was found.

Abstract

Ortodonts Orthodontist Ievads: Zobu regulējošās kapes, kas ir mūsdienīga, ātri augoša un augsti novērtēta metode zobu regulēšanā, spēj sniegt pacientiem skaidrāku priekšstatu kā izskatīsies viņa zobi pēc regulēšanas. Molāru distalizēšana ārstēšanas plānošanai var prasīt daudz laika vai papildus mehāniku. Mērķis: Noskaidrot zobu distalizācijas aktualitāti un pilotpētījumā izvērtēt izvēlētās uzslāņošanas programmas 3D Slicer mērījumu iegūšanu zobu kustībām ar zobu regulējošām kapēm. Materiāli un metodes: Pētījumā iekļauti 10 pacienti (7 sievietes, 3 vīrieši), vecuma grupā no 18 līdz 44 gadiem. Izmantota 3D Slicer programma, kur tika uzslāņoti divi augšžokļa digitālie zobu modeļi (pirms ārstēšanas un ārstēšanas laikā) un pētīts molāru rajons trīs punktos - mesio bukālais paugurs (MB P), mezio bulākā rieva (MB R) un disto bukālais paugurs (MD P). Rezultāti: Lielākās izmaiņas notika punktā MD P 1.55mm (0.59 - 2.5) distalizācijas. Mazākās izmaiņas bija MB R punktā 1.34mm (0.80 - 1.89) distalizācijas. Vidēji visos punktos distalizācijas lielums bija 1.43mm. Secinājumi: Zobu regulējošās kapes spēj veikt molāru distalizāciju vidēji 1,4mm. Introduction: Aligners are nowadays a modern, fast-growing and highly valued method of tooth movement. They are able to provide a clearer picture of how patients teeth will look after treatment. Distalizing molars may require a lot of time or additional mechanics for treatment planning. Objectives: To find the actuality of tooth distalization and to evaluate in a pilot study the acquisition of measurements of the selected layering program 3D Slicer for tooth movements with aligners. Materials and methods: The study included 10 patients (7 women, 3 men), in the age group from 18 to 44 years. The 3D Slicer program was used, where two maxillary digital tooth models of patient were layered (before treatment and during treatment) and molar region was studied in three points - mesio buccal ridge (MB P), mesio buccal groove (MB R) and disto buccal ridge (MD P) . Results: MD P changes occurred at a point of 1.55mm (0.59 - 2.5) distalization. The smallest changes were in MB R point 1.34mm (0.80 - 1.89) of distalization. On average, the amount of distalization in all points was 1.43 mm. Conclusions: Aligners are capable of distalizing molars by an average of 1.4 mm.
