In the case of natural teeth, junctional epithelium is adhered to the enamel via hemidesmosomes, and the periodontal inner tissue is protected from environmental insults. The dental implants that are currently used are problematic in that they do not adhere to the oral mucosa at the point of abutment, unlike natural teeth [1, 2]. Thus, there is an inherent risk that contaminants may pass through the interface between the implant and the mucosa and cause inflammation leading to bone resorption [3]. Therefore, it is important to develop a material that promotes contact with the tissue. For this purpose, animal experiments are usually necessary. However, animal experiments entail problems, such as ethical issues and species differences. It would be much easier if adhesion experiments could be done in vitro instead of in vivo. 3D tissue models cultured in vitro could be one of the candidates for this type of procedure. Tissue adhesion to the dental implant requires oral mucosal epithelium. However, an oral mucosal model has not been well established as yet. In this study, 3D tissue models derived from epidermal keratinocyte progenitor cells were used. Epithelium of the skin and oral mucosa were derived from the same ectoderm, and the nature of cutaneous epithelium was similar to that of oral epithelium.

Loss of alveolar bone due to the cleft can lead to problems with feeding and speech, among other difficulties; therefore, surgical closure is strongly recommended [3, 4]. Autogenous bone grafting for patients with cleft lip and palate has become a well-accepted treatment modality to restore the function and structure of the maxillary arch at the cleft site [5, 6]. However, the procedure is very invasive and the amount of collectable bone is limited. Allogeneic bone grafts may transmit diseases and can cause immune-related complications. It is therefore necessary to develop a synthetic alternative to current graft materials for bone regeneration [7]. In recent years, poly(L-lactide) (PLLA) has been widely evaluated as a scaffold biomaterial because of its impressive biocompatibility, biodegradability, minimal inflammatory reaction, and excellent mechanical properties [8]. However, PLLA is known to show poor cell–material interaction because of its hydrophobic nature and lack of cell recognition signals [9]. In order to promote cell adhesion, surface modification of PLLA is often attempted [9].
